Slide Action on Exit Cancelled by Length of Audio File

Status:  Solution to problem works but makes no sense
Problem:  Slide actions on exit designated in the Properties Inspector do not function.  Although the "jump to slide" action was selected, the transition at the end of the slide moves to the next slide. I encountered this problem as I was developing a series of slides that would supplement a single beginning slide.  Using click boxes I wanted the learner to be able to click on an item, go to a slide with more detail, then return to the original list on the starting slide.  I set the supplemental slides up in the Property Inspector--Actions to "Jump to slide" and selected the beginning slide number.  When I ran the project, the click boxes moved to the correct slides but the supplemental slides did not return to the beginning slide.  They only transitioned to the next slide.   
Solution:  This makes no sense to me and is the source of my question.  I'm using text-to-speech as a temporary method of making a rough cut at timing while I am waiting on narration files.  The audio files created by text-to-speech usually run to the end of the slide and are exactly the same length as the slide.  Grabbing at straws to fix the problem, I added 0.2 secs to the slide length so the slide timing was slightly more than the audio file.  Voila!  The selected action (jump to slide X) functions as expected.  I made the same change on the balance of seven slides and the entire routine works as designed.  I have not tested slides using imported narration or narration recorded within Captivate to see if the same problem presents. 
Why would this be?  Why would the length of an audio file prevent an exit action from functioning?
