And here's a real kicker.. I went to watch a movie on my projector which previously has been quite easy. I just plug in the projector to the displayport, open Quicktime, drag the movie window to the projector and hit full screen. My movie plays and I can still use the computer. No more - Now when I drag the window to the projector and go full screen, it does that new slide thing. It sends the movie to my MBP's monitor and turns the projector screen black. You can't be full screen with a video and use your other screen for other stuff. What in the world kind of change is that? I was so upset when I had guests over and went to use it. The only solution to get the video on the second display (projector) ended up being to use Quicklook from the finder. Ridiculous. I hope they change this.
