OK, so I just got a 17'' Macbook Pro running Snow Leopard. I work at a school that just switched from windows to Mac, and we use Smart Boards in class. I was wondering if there was any way to set it up where the projector has a completely different desktop-dock, icons, and windows included-than the computer itself. With windows, there was a simple way to set this up so I could put up questions for the students to work on and still be able to work on my own work at my desk without having to have two computers altogether. I talked to the Apple rep our school dealt with, and he didn't have any ideas... Any suggestions would be greatly appreciated?
