You cannot start an application program or it quits unexpectedly.
One of the following is probably the cause:
• The computer ran out of memory.
Quit the programs that you have open and then open the
program you want to use, or restart your computer.
Make sure virtual memory is turned on in the Memory
control panel. For more information on virtual memory, see
the “Memory” topic area of Mac OS Guide, available in the
Guide (
T
) menu.
• The program needs more memory.
Use the program’s Info window to give it more memory. For
information on increasing a program’s memory, see the
“Memory” topic area of Mac OS Guide, available in the Guide
(
T
) menu.
• The program is a non-PowerPC Mac OS compatible
application program running in emulation mode that
requires a separate floating-point unit (FPU), for example, a
68882 FPU.
Check the documentation that came with the program or
contact the program’s manufacturer to find out if the
program requires the FPU found in a non-PowerPC chip. If it
does, you may need to upgrade to the PowerPC Mac OS
compatible version of the program, or install software that
emulates a non-PowerPC FPU.
• Sometimes incompatible system extensions or control panels
can cause software problems. Restart while holding down
the Shift key to temporarily turn off all system extensions.
If your program works normally after you do this, restart
your computer again. Then use the Extensions Manager to
turn off individual extensions and control panels. For
detailed instructions, see the “Customizing Your Computer”
topic of Mac OS Guide, available in the Guide (
T
) menu.
If your program performs better when a particular extension
or control panel is turned off, contact the software’s
manufacturer for information or an upgrade.
