I have had a problem recently and wanted to see if anyone else had a similar problem or solution.
I am using Windows XP (with all the latest updates). Every time I restart the computer, it runs perfectly. But after some period of usage (I haven't figured out a pattern), certain applications (most obviously Adobe Acrobat) don't display properly. When I have a pdf open and maximized, it just shows as a blank screen. But when I shrink the application so that it only takes up a small part of the screen (~20%), then the document will display.
Any ideas? Is there some application in the task manager that I can restart when this happens to reset the drivers or something like that?
