Contrast What I do is at the slide you want it to end at, click (P) - Customize Slide. In the section MAIN - change the Display slide for (sec) to for example 180 seconds or greater. This holds the slide for 3 minutes, giving the viewer time to see added button you will add on that end slide. On that slide create new button in Object Editor, using Properties directing it to " Go to slide number " or " Go to first slide. Good question, maybe others will have a different solution that I am not aware of.. Ralph
