In my original program I intended for it to work the way it does with debug on. I might have switched things around reducing the script to a manageable size for reporting the problem. And working differently whether debug is on or off is what concerns me. The crash was a surprise and I noticed that if I tried to reload the script instead of turning debug off I got a stack error.
