No updates as far as cause or cure.

I did notice that shutting off aero themes and using a basic has improved the performace some where the problem rarely happens, one thing I found was that while window swapping I would often mouse over my start menu bar to click over to firefox or some othe program and then the wow's would lock up or see the graphic glitch issue. From what I've played with it seems that something is causing the issue when you try to incorporate other stuff while window swapping.

Careful movement of my mouse Has lessened the problem occurrance
