Just started to look around the forums to see if other people were having this problem too, and this is my first hit. I've had to unload Windowblinds on my main PC because of this problem, almost exactly as described - parts of windows not updating properly, showing the contents of windows either underneath them or that were dragged across them. The minimize/restore generally works, but I hate doing that every time I switch windows, and dialog boxes (like the ones that ZoneAlarm pops up) are a particular problem - sometimes I know they're there (rotating through the active windows with ALT-TAB), but I can't view or access them, which with something like ZoneAlarm can effectively lock me out and force a reboot. WindowBlinds loads ok at startup, but within no more than twenty minutes, often much less, I'm having trouble viewing some of my application windows.
I recently replaced my NVidia FX 5700 Ultra with an ATI Radeon X1600 series (both with current manufacturer drivers), but the problem is still happening. I've been an Object Desktop subscriber for years, but this is happening so frequently that I've basically given up (reluctantly) on trying to run WindowBlinds. Help? I don't see any recent responses to this thread (or what look like official answers from Stardock), which doesn't give me a warm fuzzy feeling...
