This is just a quick question: I have two monitor set up (my Macbook Pro is attached to a Cinema Display) and I often watch full screen videos or movies in the second monitor while using the primary monitor to work. However, in Lion, full screening Quicktime causes it to shift to a new Space and assigns QT to the primary desktop. Is this a limitation that was looked over with Mission Control and Quicktime or is there a way to prevent this behavior? Thanks guys Just my 2 cents on MC while I'm here: While I love Mission Control and it takes better advantage of gestures and Spaces (and works especially well on laptops), I do miss the grid. I think Apple really neglected support for full screen apps on Mission Control in multiple monitor set ups, though, too. What do you guys think about it?
