I can't figure out how to get full-screen mode to function. I hit Ctrl-F, the window takes up the full screen, but I don't see the blue arrow and I can't click on anything or move anywhere. I am using the Windows demo version and trying to check out how I would share this with co-workers, but right now looks like I can't do anything with it. Any ideas why this isn't working? Does it not work on the demo version or is there something else causing this?
