Well, heres the problem. When playing Oblivion (Or Fallout3), and just simply fighting someone, sometimes, in the top Left corner of the screen, I will see my Default Mouse Pointer. If I click, it minimizes. This is annoying, and I cant find any kind of fix. Help would be amazing. If you need anymore info, please just ask.

You use Xfire, correct?
