hmmm.. My laptop did the same thing a couple of times.
I didnt have to reboot I just managed to find my way around the desktop to change the screen settings ( change the resolution or bit depth ) which cleared up the display.
The odd thing is that now all the demo's work fine.
I wonder if it was the bit depth of the display that caused the problem...
When I get some time I'll try various settings to see if I can recreate the problem.
