property sheets”, page 12).
2 Clear one or more check boxes, starting with Use device bitmaps caching. For more
information, see context-sensitive help.
3 Click OK � Close to accept the changes. (Depending on the feature you disabled, you
may have to restart your computer for the changes to take effect.)

the Web site of that manufacturer for the latest display driver. A display driver provided by
the manufacturer of your computer is more likely to be tested with your computer model.
