I am just getting into the OpenLP on my new Mac Pro. The Menu Bar is across the top of the screen on the presentation screen which is NOT professional, so would like it to go away. I have tried the Control/Command +F for Full Screen, but it doesn't work. The O/S is Maverick 10.9.2. Is there a switch somewhere in the deep reaches I haven't discovered (uncovered). Sure would like to have the Menu bar hide on the presentation screen.
