MultiFinder, MacPaint, and QuicKeys - If you have set up a COMMAND-Q keystroke to quit applications, do not quit MacPaint with a COMMAND-Q when using MultiFinder. If you have other applications open such as MS Word and return to the Finder to launch MacPaint to create or examine a MacPaint document and then hit the keystroke COMMAND-Q to quit MacPaint, your Mac will reset and if you have not saved changes to your open documents all these changes will be lost!
