m Check for multiple System Folders on your startup disk, using the Find File command in the
Apple (K) menu. Throw away extra System Folders (ones without an icon on them). The System
Folder that your computer is using has a small computer icon on it.
m Check for viruses on all your disks, using a virus-detection program. Eliminate any viruses the
program finds.
If a problem recurs when you are using a particular application, try the following:
m Consult the documentation that came with the application to make sure you are using it correctly.
m Check for multiple copies of the application on your hard disk. If you have more than one copy,
select each one and choose Get Info from the File menu to check the application’s version number.
Keep one copy of the latest version and throw away all other copies.
m Reinstall the application from a known good source such as the application’s original disks.
m Increase the application’s memory. Quit the application, select its icon, choose Get Info from the
File menu, and type a larger number in the Preferred Size box.
m Contact the manufacturer of the application or the place where you bought it to find out whether
the application contains software errors or “bugs” and whether an upgrade is available.
m Check that the application is compatible with the version of system software that you are using. (See
the application’s documentation, or contact the manufacturer of the application or the place where
you bought it.)
m Make sure your control panels and system extensions (especially any that you recently added) are
compatible with your applications. See “Checking Your System Extensions” in Chapter 13.
