I had XP Home SP1 on my laptop before, and it supported (in teh settings mode under desktop properties) use of two monitors at once, plugging another monitor and using it as well as my laptop screen. Was able to drag from screen to screen. Was that a feature updated by SP1? Because my version of XP Pro doesn't allow such a thing to happen. Hopefully the SP2 that is installing as I type this will do it....anyone know?
