Thank you for the responses. I have looked at the event handler phases but didn’t recognize anything that may cause a problem. The issue arises after I have looped through the scenes 3 times. As you can see, most of this is just cut and pasted sample code. Sorry for posting so much erroneous code. I am just not sure where the problem is.
