Solution:
When you format disks on a DOS computer, always
format standard double density disks in the 720K
format. Always format high density disks in the 1440K
format.
Tip:
If your DOS disk has been formatted incorrectly, use a
DOS computer to copy the contents to a correctly
formatted disk.
Tip:
Make your life easy and purchase pre-formatted disks.
Problem:
The pointer (mouse arrow) freezes on the screen.
Cause 1:
Your mouse and/or keyboard cable may be loose or
disconnected.
Solution:
Press the power button on the front of the computer.
Once your computer is turned off, reconnect the
cable(s). You will lose any unsaved work, but
do not
connect or secure cables while the power is on
; you
could damage your computer.
Cause 2:
Signals from the mouse are not reaching the computer,
either because the mouse needs cleaning or because
there is something wrong with the mouse.
Solution:
Clean the mouse according to the instructions in
Appendix A.
Solution:
If you have another mouse or pointing device, try
connecting and using it. (Always turn off the computer
before connecting a mouse or pointing device.) If the
new device works, there is something wrong with the
mouse you replaced.
Cause 3:
Your currently active software application has a
problem.
Solution:
Press the restart button on the front of your computer:
a simple restart may correct the software error.
Tip:
Press Command-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, then restart.
Cause 4:
You may be using a software application or system
extension that is incompatible with the system
software.
Solution:
Make sure that any software you install on your
computer is compatible with the system software.
