I have used windows 8 consumer preview since it came out and has not upgraded to windows 8 release preview. I just noticed a strange thing. Windows will freeze every time I put the mouse on any of the 4 corners of the screen. After a few seconds it unfroze and I could start using it again.
I have an ATI 5870, which DOESNT work out of the box. All I saw was the mouse pointer, everything else was black.
Had to use the MB display port in order to setup windows.
Anyways, I installed the ATI drivers for Windows 8. My card started working again but the corners still froze the OS.
I updated Windows and this issue was gone.
Video card stopped working again, same issue with the black screen. I went back to the MB display port and the corners are freezing again.
Anyone else have these issues? No idea how to get my card working again since I've updated to the latest drivers.
