It's a good idea to save your work frequently, and keep current backup copies of your hard disk data. When a system crash occurs, you'll lose less data if you've taken these precautions.
If you're getting system errors frequently, investigate these possibilities:
• Try to open the document with a current version copy of the application.
• Try opening other documents with the same copy of the application.
• Check to see if the document size exceeds the application size limits.
• Boot your system with extensions off (restart while holding the Shift
key down).
• Any changes (new Control Panels, extensions, etc.) you've made to
the system might give you a clue to the cause of the crashes.
• Make a note of the desk accessories you had open at the time of the
crash and exactly what you did before the crash.
• Also make a note of the error ID or text, and the version numbers
of the application and system software you were using.
• Try to recreate the problem on another Macintosh.
• Cleanly install your system software and try the application again.
