Hi,
I have had the same problem with two brand new FE11H laptops:
When media centre is running in a window (not full screen) it begins to flicker - a lot - when I open a menu/right click on the desktop.
Strangely, I can turn the visulaiser on for music in the MCE window and the flicker will stop. It is very noticable and has caused the machine to crash a few times.
Has this happened to anyone before and any ideas about whats wrong?
Thanks
