Additional Information:
	
FWIW, there are no problems when the machine is undocked and no external
monitor is attached. I'm guessing this is perhaps related to the
LCD/ext.monitor issue with the ATI driver on 7.1. It would be nice if some
intelligence could be built-in to know whether the LCD or external monitor
is active and act appropriately. Or will 4.1.0 fix this issue?
