I need help please. I am using my macbook pro, and my projector. I want to to extend my desktop onto the project one. I want to play imovie in fullscreen on the projector, and I want to be able to do other stuff on my main screen. When I drag the program over to the projector, I click full screen, and it puts it on full screen on my main screen, and not the projector. I want to have the imove running in full screen and I want to be able to go on something else on my mac screen without exiting out of full screen on the projector. How can I do this?
