Thank you, Ray and Peter, for your assistance. Following Peter's suggestion so that I can use it in a similar fashion for future shows I did as suggested. However, the Set End of Last Slide to End of Music is greyed out. I turned the Synchronize back on, hit the Start Preview With Current Slide icon, and the timeline for the show increased from 275 minutes to 1102'02 ". When I hit preview the music starts but the show will not move off the first slide. I only have one piece of music, 3'09" long and i wanted the 70 slides to move quickly through that 3 minute timespan. What do I do now please?
