When I use Insert > Object in order to show a 4/3 presentation on a 16/9 slide, the 4/3 presentation in Slide Show View jumps to 4/3 full screen mode, thus showing black bars on the left and on the right.
Is there a way to have the 4/3 presentation play within the 16/9 frame, so that you keep seeing the 16/9 background?
Thanks!
