On my laptop when I disconnected my external monitor I had to get into Windows and make the laptop monitor the #1 screen. I think that is what Matt is saying. Just because your monitor is not connected doesn't mean that Windows knows that it is disconnected, i.e. you have to tell Windows that the external monitor is no longer available. Doing this should solve your problems.


Whenever I get something stuck in the back of my throat, I dislodge it by drinking a beer.
It's called the Heineken Maneuver.
