I'll look into the updates and any changes I may have made (I plan on backing up anything I need and completely starting from scratch with this computer, it's got a ton of junk on it but it's pretty "clean").
It seems to happen (I need to test this theory) with the first maximized window I close, I'm not sure with any window, but I know it happens with folder windows (not firefox,word, or other program windows). It may have to do with some process running when I first turn the computer on, I need to look into that as well (been awhile since I've done maintenance, this is the only problem I've really been having).
I may not have SP3, so I really need to look into that. I'll edit when I find out more, thanks for your reply.
