Thanks to everyone for all the information. This has been a learning experience and I will make changes in the future. Like Jeff Evans suggested, I was able to change duration of the last slide and that made the difference. Seems elementary now. The presentation finishes out smoothly and comes to a nice close. I will also be careful in the future to check music durations, etc., as well as convert music files to MP3. I didn't know what software programs were available for that and now I'm in business. This was my first post on this site and all of you really helped me out. Thanks, Bill P.S. - If you're in to nature/wildlife photography, my website is www.wmwiley.com
