I'm using a HP Compaq 6510b laptop running Windows Vista 64-bit with an additional 24" screen.
Windows is constantly forgetting the screen layout, even though I didn't disconnect anything. A simple reboot or waking up from standby is enough so that the screens are rearranged.
Do you have any solution to this?
My inconvenient solution for now is to disable the build-in screen and work just on the external screen. But I'd like to use both.
