System 7.5 Update 2.0: What's New in This Update (3 of 3)
DISCUSSION
This file is one of three Read Me files that describe System 7.5 Update 2.0. This three-part document provides details about the changes provided by this software update. Another Read Me file, Installing This Update, summarizes the enhancements of this update and gives instructions for installing the update. What's in this document (part 2 of 3) Changes to SimpleText Includes SimpleText version 1.3.1, which supports QuickDraw 3D. Includes the following enhancements introduced with the version of SimpleText provided with System 7.5 Update 1.0: Changes to the Launcher This Update includes Launcher version 2.8 which incorporates minor behind the scenes changes not likely to be visible to users. Launcher version 2.8 also includes the following fixes and functionality, introduced in System 7.5 Update 1.0: - Supports Macintosh drag and drop, making it easier to add or remove items. To add an item: Open the Launcher and drag the item into the Launcher window or onto a category button. The system creates a new Launcher button for the item by placing an alias in the Launcher Items folder. The original item remains on your hard disk. To remove an item from the Launcher: Hold down the Option key and drag the button out of the Launcher. To move a Launcher button to a new category: Hold down the Option key and drag the button to a category button along the top of the Launcher window. To open a file using the Launcher: Drag the files icon onto a Launcher button that represents an application program. For example, you can open a SimpleText file by dragging its icon onto the SimpleText button. If the program the button represents can open the file, the button is highlighted when you drag the file to it. To put a file into a folder: Drag the files icon onto the Launcher button that represents the folder. To resize the currently visible Launcher buttons: Hold down the Command key and click inside the Launcher window. Then choose a new size from the pop-up menu. To open a category buttons folder (located in the Launcher Items folder): Hold down the Option key and click the category button. Other new or changed components Includes Open Transport v.1.1, a major re-implementation of the network system software for use on all 68030-, 68040-, and PowerPC-based computers except the desktop 5200, 5300, 6200, and 6300 series computers. After an Easy Install, Open Transport will be active only if it was active before the update was installed (it cannot be active on desktop 5200, 5300, 6200, and 6300 series computers). For more information, see the Open Transport Information folder, inside the Apple Extras folder. Includes a small application called Network Software Selector (NSS), which enables users of 68030-, 68040-, and early PowerPC-based computers to choose between Open Transport and classic AppleTalk if both are installed. (You must restart the computer for the change to take effect.) PCI-based computers support only Open Transport. NSS is in the Apple Extras folder; information on using it is built into the application. NSS is intended to ease the transition to Open Transport by allowing you to use the older networking software if there is a compatibility issue with an application and Open Transport. Once the issue is resolved, you should switch back to Open Transport. Note : Because MacTCP is incompatible with Open Transport v.1.1, MacTCP is disabled any time Open Transport is selected using the Network Software Selector. (Open Transport uses the TCP/IP control panel instead of MacTCP.) If, however, you reselect classic AppleTalk, MacTCP is enabled again. For users of the older networking software, this update includes MacTCP 2.0.6, which Includes SerialDMA 2.0.2 for use on all PowerPC-based computers, the Centris 660AV, Quadra 660AV, Quadra 840AV, as well as the corresponding Performa and Apple Workgroup Server products. SerialDMA provides a complete rewrite of the DMA serial driver which originally accompanied these computers, thus fixing the occasional system hang, communications timeouts, poor communications performance, and other glitches. The new SerialDMA 2.0.2 driver not only corrects these issues, but also exceeds the performance and reliability standards for serial communications on the Mac OS platform (providing support for speeds of up to 230,400 bps). SerialDMA 2.0.2 is native on the PowerPC-based computers. Includes a new version of Apple Modem Tool (1.5.5), which supports 115.2K and 230.4K connections on SerialDMA 2.0 machines. Includes the latest version of PC Setup (v1.0.7) for use with all DOS Compatible Mac OS computers. Includes Screen control panel version 1.0.7. This new version does not crash if its in the System Folder of a Macintosh SE during startup or when its opened on any 68000-based Mac OS-based computer. Includes File Sharing 7.6.2, which includes several improvements over previous versions. Now, when file sharing is turned on, removable disks and CD-ROM discs will automatically be shared (except for audio CDs, which will no longer be shared). To eject a removable disk or CD-ROM disc, you no longer have to turn off File Sharing, as long as no other user is currently connected to the shared volume. Includes a faster version of the AppleShare Workstation client software. The new version performs read-ahead and write-behind caching, allowing the Finder to write to a local volume while reading from a remote volume (and vice-versa). The new version also briefly caches some information from the desktop database to avoid unnecessary hits to the disk. Includes Apple Video Player 1.4. Miscellaneous fixes and enhancements The Shut Down warning, which appears during startup if the computer was shut down improperly, dismisses itself after two minutes so that startup isn't delayed when no one is around to read the message. Note that this warning can be turned off completely in the General Controls panel. Includes Macintosh Easy Open 1.1.2, which fixes delays when dragging Finder folders. The dialog box displayed after the keyboard Power key is pressed dismisses itself (simulating a click on its Cancel button) after one minute. Fixes an issue with the Power key. In previous versions, if the Power key was held down just a little too long, the hardware could miss the release of the key. If the next key pressed was the Command key, the hardware would mistakenly think that Command-Power had been pressed and would bring up the programmers window (or MacsBug if it was installed). Color Picker no longer crashes during startup. There is an issue with certain third-party SCSI drivers that mark the drive as removable at the beginning of startup and later mark it as non-removable. Because Color Picker creates an alias to itself during startup, the change to non-removable prevented the Color Picker alias from being resolved later. Color Picker now handles the failure to resolve this alias. Fixes an issue introduced by System 7.5 Update 1.0 that prevented 2-byte characters from being used when naming a DOS disk. Fixes an issue that allowed the Menu Manager to use an unlocked handle. This fix will eliminate some crash issues, especially when using certain pop-up menus. Changes several video drivers to provide better support for new monitors introduced since System 7.5 was released. Handles low-memory situations better than previous releases of Sound Manager. Fixes an issue that allowed the sound volume to be lower after restarting than it was before restarting; volume should now be properly preserved when restarting. The state of the Mute checkbox in the Sound control panels Volume window is now preserved across restarts. Fixes an issue that allowed QuickDraw to leak about 50 bytes of memory in some isolated circumstances. Fixes an issue that allowed a non-existent disk drive to show up in Disk First Aid. Fixes a crash issue in the Communications Toolbox that happens if there are more than about 600 zones on a single network. The new limit is just over 8000 zones. Fixes an issue on the 630 and 5200 series computers that would cause them to ignore the infrared remote control. Fixes an issue that made it take two attempts to unmute the sound using the infrared remote control on 630 and 5200 series computers. Presents a dialog box that advises users that audio CDs cannot be shared if an audio CD is selected and the Share a Folder or Share a Folder (no Guest) automated task is executed. (In the past, the system would hang in this situation.) Fixes a bug that caused the wrong font to be used in some cases. Fixes an issue that allowed a garbage pattern to be used when redrawing the pattern in a scroll bar. Fixes an issue with submenus drawn too large or not drawn at all. Fixes an issue that sometimes caused the startup progress bar to draw improperly. Fixes an issue in WorldScript Power Adapter that could cause text to wrap randomly in Text Edit fields, or to appear garbled. Plugged a small memory leak that sometimes occurred when resizing a window. The Power key can now be used to turn the computer off. To shut down the computer, press the Power key. When the dialog box appears, you can shut down your computer, restart your computer, put it to sleep (if it supports sleep), or cancel the shutdown. PowerBook 100 series computers do not have a Power key on their built-in keyboard, but if you attach an external keyboard, you can use the keyboards Power key (as just described) to turn off the computer. This functionality is not supported on the Macintosh Plus. The Synchronize Folders AppleScript automated task handles nested folders properly. A new AppleScript automated task Share a Folder (No Guest) lets you automatically share a folder with the Guest access disabled. Improves system stability when memory is very low. Fixes a potential crash issue when shutting down or restarting Japanese systems with QuickTime 2.0 installed. Fixes a potential crash issue when pasting large amounts of data. No longer opens the wrong original when you select an alias on the desktop of a disk other than the startup disk. No longer interferes with custom colors that some applications use in the Open and Save dialog boxes. Fixes a potential crash issue that occurs when Stickies opens with a collapsed note window. Fixes an issue that would allow the Options button in Sound control panels Sound In window to be dimmed when it should be enabled. Fixes sound issues in the Jigsaw Puzzle (caused by a third-party extension). PowerTalk Catalogs Extension version 1.1.1 no longer displays an out-of-memory error when you open a catalog. PowerTalk AppleMail version 1.1.2 works better on systems with many fonts installed and defaults to sender only for mail replies. PowerTalk DigiSign Utility version 1.1.1 improves printing on HP DeskWriter C and 550-style printers. Direct Dialup version 1.1.1 works better when dialing using a long string and wont time out while sending a large letter or a letter with a large enclosure. Fixes a potential crash issue that occurs if both PowerTalk and At Ease are installed. While PowerTalk and At Ease no longer crash when used together, accessing all of Power Talks functionality requires the Finder (open the Special menu in At Ease and choose Go To Finder). Command-Option-Space bar no longer changes the keyboard layout if multiple layouts are installed. This avoids a conflict with some popular games that used these keys for controls within the game, resulting in a seemingly random layout being selected once the game is finished (during the game, the selected layout would change any time the three keys were pressed at once). If you want this functionality restored, open the Keyboard control panel and click the checkbox at the bottom. The conflict with certain games will exist as long as this box is checked. WindowShade version 1.3.1 fixes a potential crash issue that occurs when memory is very low. Macintosh Easy Open version 1.1.1 works better with drag-and-drop on document converters. Fixes an issue in the Menu Manager that could cause memory fragmentation within an applications heap. File Sharing no longer causes a crash when Find File is searching a remote volume using Apple Remote Access. Fixes an issue in file sharing that caused some files not to get copied. (The symptom of this issue was a dialog box stating that the file could not be copied because it couldn't be found.) Files no longer needed The Update automatically deletes the files listed below, unless you renamed any of them, in which case, you should remove the files. Several standalone files are now merged into the System 7.5 Update Enabler or the System file.
