m If the problem recurs, you may need to reinstall system software. See
Chapter 7, “Reinstalling Your Computer’s Software,” for instructions.
m If the bomb only occurs in one application program, try reinstalling the
program from the original disks. If reinstalling doesn’t solve the problem,
contact the manufacturer of the program.
The pointer ( 8 ) doesn’t move when you move the mouse.
One of the following situations is probably the cause.
m There is a software problem. Try 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 by Restarting Your Computer” in
the section “If You Have Trouble” earlier in this chapter for instructions.
m Follow the suggestions in the previous entry, “A Dialog Box With a
Bomb Appears.”
m The mouse or keyboard is not connected properly.
Turn off the computer by pressing the power key (and then press return
to choose Shut Down), or if that doesn’t work, press the standby power
button (®) at the back of the computer. With the computer off, check
that the mouse and keyboard cables are connected properly. Then restart
the computer.
IMPORTANT Do not connect or disconnect the mouse while the computer is
turned on. You may damage your computer.
m Signals from the mouse are not reaching the computer, either because the
mouse needs cleaning or because there is something wrong with it.
Clean the mouse according to the instructions in Appendix A of this book.
If you have another mouse or pointing device, try connecting and using it.
(Turn the computer off before connecting it.) If the new device works, there
is probably something wrong with the mouse you replaced.
If none of these procedures solves the problem, consult the service and
support information that came with your computer for instructions on how to
contact an Apple-authorized service provider or Apple for assistance.
