Troubleshooting
On the Macintosh, use the Extensions Manager
•
control panel or a third-party extension manager
utility to temporarily turn off all extensions except
your CD ROM extension. On most Macintoshes,
this is the Apple CD ROM extension. Then
reinstall Adobe Photoshop.
Check for new software or setting conflicts
Problems with Adobe Photoshop can often be
traced to recent installation of new software or
utilities that are running at the same time as
Photoshop. If you have recently installed new
software or changed other system configuration
settings, such as your monitor setting, try de-
installing the software or restoring your original
settings. (If you de-install software, you might
need to reinstall Photoshop following the instruc-
tions in the previous section. This will ensure that
any Photoshop files that might have been damaged
by your new software installation are restored.) If
the problem disappears, you can try reinstalling
the problem software or system utility or contact
the manufacturer for a new version and for
compatibility information.
Check for the current video driver (Windows only)
In Windows be sure you have a current video
driver that's written specifically for your video
card. To obtain the latest video driver for your
hardware, contact the manufacturer of your video
card.

Explorer to move the shortcut files in the
Windows\Start Menu\Programs\Startup folder to
a different folder. On the Macintosh, hold down
the Shift key and restart the computer to restart
with extensions off. (See your Windows or
Macintosh documentation for more information
on deactivating startup software.)
If the problem disappears after restarting
Photoshop, try restarting your computer with
selected startup items reactivated until you have
identified the problem software. You can then try
reinstalling the software, or remove the software
and contact the software manufacturer for a new
version and for compatibility information.
Deactivate the preferences file
your problem is caused by a corrupted preferences
file, quit Adobe Photoshop, deactivate the prefer-
ences file, and restart Photoshop.
To deactivate the preferences file in Windows,
rename the Adobe Photoshop 5 Prefs.psp and the
Color Settings.psp files (located in your
Photoshop\Adobe Photoshop Settings directory).
Note: To make it easier to figure out which files
you are seeing, start Windows Explorer and choose
View > Options. Then deselect the option Hide
MS-DOS file extensions for file types that are
registered.
