I'd like to enable multiple monitors on my Dell Laptop. It is attached to a 19" viewsonic external monitor. Now, I can enable multiple monitors where the laptop screen is the primary display and the external monitor is secondary (the start-menu and everything is on the laptop screen). Is there a way to switch the primary display to the external monitor? I'd like to do most things on the external monitor and leave the laptop screen for things like MSN messenger, Winamp, and other crap. Thanks.
