When I use a large number of slides (20-30), the slide show gets hung up. By that I mean that when a random slide is chosen for a second time, it keeps coming back to that slide every other transition. Then, at the end of the slide show, the show stops regardless of the setting chosen for "Return to the beginning of the slideshow after last slide". This is not an issue when only 10 or less slides are used. Anything you can do to help?
