We have Macintosh computers (PowerBook 170 and IIcx) running System 7. They will not retain default settings, such as changes to Views (like font size) or the Trash warning. After a restart or shut down, the settings return to default. Resetting the PRAM does not help.

It sounds like you might have a corrupted Finder Preferences file, found by following this path:

System Folder
- Preferences
--Finder Preferences

Try the following procedure:

• Put the existing Finder Preferences file in the Trash can .
• Restart your computer. (This will automatically create a new Finder Preferences file.)
• Empty the Trash can.
