Apple Power Macintosh 7200 - Manual (Page 90)

After you open an image on a Photo CD, the image is scrambled, colors are displayed
incorrectly, or no image appears in the window.
m The program you are using may not be designed to work with large (high-
resolution) image files. You can open the image with another program or
you can assign more memory to the program. (For more information on
managing memory, see the “Memory” topic of Macintosh Guide, available
in the Guide [h] menu.)
After you open an image on a Photo CD, your system is “frozen” and does not respond
to any input, or you have a “bomb” message on your screen.
m Restart your Macintosh. The program you are using may not be designed
to work with large (high-resolution) image files. You can open the image
with another program, or you can assign more memory to the program (see
the “Memory” topic of Macintosh Guide, available in the Guide [h] menu,
for more information on managing memory).
If your computer’s performance decreases
If you notice a decrease in your computer’s speed and general performance
after you add special software like a control panel, system extension, or
custom utility, it may be because this software does not work well with Power
Macintosh computers.
m To find out if a system extension or control panel is the problem, use the
Extensions Manager control panel to turn off system extensions. Next, use
the Extensions Manager control panel to turn the system extensions and
control panels back on one at a time, restarting and checking your
computer’s performance each time until you identify the software that is
causing problems. Contact the software’s manufacturer for information or
an upgrade.
m To find out if a custom utility you’ve added is the problem, drag it out of
the System Folder. (This software may be in the Control Panels folder or
elsewhere inside the System Folder.) Next, restart your computer and check
its performance. If there’s an improvement, the new software was probably
the cause of the problem. Contact the software’s manufacturer for
information or an upgrade.
If you still do not notice an improvement, follow the instructions in
“Installing or Reinstalling System Software” later in this chapter to reinstall
system software on your startup hard disk.
