I have a problem with windows Aero too but that is due to VLC. I am changing the same by tab key and it crashed. I bought a computer with Windows 7 and two days ago early windows aero worked very well in 3D with dynamic thumbnails. Yesterday I limit left on standby overnight and turning it back on Windows Aero no longer working. And the 3D effect but a bar with icons and more dynamic thumbnails does not work at all. I have a Geforce 7500 card which shows that I do not have limitation in the system.
