Apple has added a new article to the Knowledge Base regarding a keyboard shortcut that can quit the Classic environment without notice. Appleis Knowledge Base (sometimes referred to as the KBase) is a central location for all of Appleis support documents and other important information.

If the command Command-Option-Shift-Q is used while using a Classic application, the Classic environment will force quit, losing all unsaved data. The solution is to avoid using this key comination until Apple provides a fix. From Apple:

Symptom

Using the keyboard shortcut Command-Option-Shift-Q in Mac OS X 10.2 while using the Classic environment immediately causes the Classic environment, and any applications open it, to quit without warning.

Important: Any unsaved data in open Classic applications will be lost when the Classic environment quits.

Products affected

• Third-party Classic applications that use the Command-Option-Shift-Q keyboard shortcut.
• Mac OS X 10.2 to 10.2.2

Solution

Apple is investigating this issue and will update this Knowledge Base document when more information is available.

Until a permanent solution is found, you should avoid using the keyboard shortcut Command-Option-Shift Q when using Classic applications.

To restart the Classic environment click Restart in the Classic preference pane.

Note: This only restarts the Classic environment, it does not restart the computer.
