Sorry for the long time between replies, I've been on other projects for a while.

I only set the transition time lower as an experiment to see if it would work. My problem is with several slides on this project that have seemingly long delays before transition.
One slide in particular runs for 37 seconds. The audio runs for 36 seconds. The transition is set to 38 seconds with 0.1 transition time. But the slide doesn't go on to the next one until 43 seconds. Other slides have more of a delay than I would like also, but this is the worst one. Is there anything I can do to get rid of the long pause?
