I just got my Neo a few days ago, and I'm mostly happy, but I'm having one super annoying issue. I like to keep certain apps like Mail and Message in their own space and then use Mission Control to swipe through. Several times when I switch to a full-screen space, the screen is just black and non-responsive. The only way to get the app back is to either exit full screen or switch back and forth again. Has anyone else had this issue?
