Black squares covered all my desktop icons except the trash bin and the computer ones. I don't recall doing anything weird. I rebooted and all that (several times).
My System:
Windows 7 SP1
Dual Core E8300
8 GB RAM
nVidia GeForce GT 570, two monitors
Logitec setpoint and lsd core programs for G510 & G9x gaming keyboard/mouse.
I have a bunch of programs, too many to list which include a lot of games installed (over 60).
Anyone else had this problem?
