Easy to get the audio out of sync with the graphics (Repost)

This is an attempt to help Pre-Kindergarten and Kindergarten children learn about the numerals and numbers from one to 9. The problem is that this age group would be prone to just pressing buttons and it is easy to get the audio out of sync with the graphics. I have played around with Pause[different values] and Enabled->False/Enabled->True as well as SynchronousUpdating -> False. I was hoping that someone might be able to tell me whether I was on the right track; if there is a different function I should look at; or (most important) if what I am trying to do is not doable. I would also appreciate if someone could tell me a way to follow the flow of the way the code is read by the computer, that would give me an idea of where to best place Pauses, etc. (I want to thank John Fultz for contributions previously made to this manipulate.)
Thank You, Clif McInnis
