Apple Macintosh Performa 6100 Series - Manual (Page 68)

A dialog box with a bomb appears.
Your system has a software problem.
m Write down what you were doing when the message appeared and the text
of the message.
m Restart your Macintosh. (See “Start Over” in the section “When You Run
Into Trouble” earlier in this chapter for instructions.) Most software
problems are temporary, and restarting usually corrects the problem.
m Check the startup disk and application program you were using when the
dialog box appeared. Make sure that all programs, desk accessories, and
system extensions you’re using are compatible with the system software.
Reinstalling the system software may correct the problem.
m Sometimes incompatible system extensions or control panels can cause
system software problems. Restart while holding down the Shift key; this
temporarily turns off all system extensions. If your computer works
normally after you do this, use the Extensions Manager control panel to
turn on extensions and control panels one at a time. Restart after you turn
on each extension. This procedure should identify incompatible extensions
and control panels.
For information on using the Extensions Manager control panel to manage
system extensions, see the “Setting Options” topic of Macintosh Guide,
available in the Guide (h) menu.
m If the problem recurs, you may need to reinstall system software. See
“Installing or Reinstalling System Software” later in this chapter for
instructions.
The pointer ( 8 ) doesn’t move when you move the mouse.
One of the following situations is probably the cause.
m Your system has a software problem. Try one or more of the following:
Press x-Option-Esc to quit the application program in use when the
problem occurred. If this works, you can save the documents open in other
programs before restarting.
Restart your Macintosh. See “Start Over” in the section “When You Run
Into Trouble” earlier in this chapter for instructions.
