I noticed that at the bottom of my slides screen there is a gap. It looks like the window that opens for the slides is not going full screen.
Hi Aaron
I can get this effect if I change my setting from 4:3 to 16:9.
Mike, are you sure they aren't talking about the thin white strip at the bottom of the picture. Look closely. I didn't catch it at first. I don't think they were referring to the black at the top and bottom of the slides. Just my interpretation.
Josh you are correct. I was not talking about the black strips above and below. I was talking about the white stripe on the bottom, there is also a thin strip of the background that shows below the white stripe.
