I ran Thief 3 on a Windows 8 computer as well as a Windows Vista 32bit and was able to minimize the game just fine (though the performance was horrific).

Now I am trying to run the game on a Vista 64bit and it fights me every time I try to minimize the game. It instantly decides to bring itself back to the front and I can't figure out why.

Tips?

Edit: I should have made this a problem thread.
