Judy is not asking to see the .story so she can know what the problem is. You already described that. She is asking for the file so someone can look at it and tell you WHY it’s doing what it’s doing, and how you can fix it.
However, according to your second post, it appears you have found the solution. If you can make it function by re-creating the object, that indicates some sort of corruption somewhere in the slide, object, or triggers. That is not an infrequent occurrence in SL, and, as you discovered, has a pretty simple fix.
