TOPIC

    Opening a Classic application that uses the Mac OS 9 Theater Mode extension (such as QuickTime Player 4.1.2) may interfere with the use of other Classic applications.


DISCUSSION

    Symptom

    Other Classic applications do not open as expected after using a Classic application that calls on the Mac OS 9 Theater Mode extension. QuickTime Player 4.1.2 uses the Theater Mode extension.

    Products affected
    • Mac OS X 10.0
    • QuickTime 4.1.2 (Classic)

    Solution

    Use the QuickTime 5 Player included with Mac OS X.

    If the issue occurs with a different Classic application, disable the Theater Mode extension using the Extensions Manager control panel in Classic. You must then restart Classic.

    Note: The Theater Mode extension is only present on computers that use it.
