hey,.
I don't use that, and never tried(would LOVE to though.. ),.... but, once I was at the computer show in NY and they had this computer with 4 screens... ummm I'm not sure what card there was inside, but it looked like the whole video didn't have to do with any other programs... It just worked like it usually does.. in 1 screen mode... you just drag the program window through, and it appears on the other one... kinda cool... lol
perhaps wait for some more responces.... (I wouldn't trust myself if I were you.... )
