I've been having an issue for quite awhile where windows will get stuck on top. What I mean is I might have firefox open, and then open a windows explorer window, and it's underneath the Firefox window. I have to minimize the other window to see what I just opened. This isn't application specific, as I've had it happen with Outlook, Chrome, the Command Prompt, and a few other programs. If I close the application that's stuck on top and reopen it, it's fine again. I've checked all the "Stay on Top" options associated with that program, and they are always unchecked. Here are some steps I've taken to correct the issue:
Upgraded to Windows 8
Updated all my drivers
Rolled back drivers to old versions
I currently am setup in a dual monitor environment, and I've exhaustively pursued a solution, and haven't found one yet. Any help would be appreciated.
