I'm fairly new to Mac and having a dual monitor setup, but I have my secondary display working and arranged above my laptop. I want to be able to move between screens on the laptop and have the secondary display on the TV freeze on that document so that I can read what else I need to search for. I have tried turning 'Mirroring' on and off but it doesn't seen to stop the secondary display.
I am on Mac OS X 10.7.5 (MacBook Pro 13" Late 2011)
