Like many other's before me, i am facing a sudden issue with Windows Aero.
Windows Ultimate x64.
With current Updates on SP1.
Ati Radeon 5770 HD 1GB GDDR5 PCI-Ex Card.
16GB Transcend DDR3
Intel I7 2600K
I am not sure what triggered the event.
Last i did was install Zoo Tycoon Complete.
I am pretty sure, after that is when the desktop didnt restore to default pixel, i manually overran the graphic setting to restore to 1920*1080.
Other than that nothing.
Do let me know if you need any other detail..
Without the transparency, it is a lil odd working on the machine.
