I am running Win2000 with service pack 2. On most days my system gets into a state where the text that should be displayed in a window is invisible. You can cursor around as if the window has text in it, but you don't see anything. Once this happens it effects many of the applications that I'm running - including MicroSoft Word, Internet Explorer, Microsoft Visual Studio. Has anyone seen this before, know how to fix it, or have suggestions on how to debug this problem?
