Can we see your script?
I found the reason and I am quite chagrined at the moment.
The save button was copy/pasted from the cancel button...and I forgot to update the perform script setting...

So sorry to waste your time.
Thanks for the update. I looked at the script and didn't see anything obviously wrong.
I do know that in the debugger it's easy to step right past a Pause. Also, in debugger if you're referencing a script in another file, it will bring that file's window to the front, which isn't the case without debugger. But it didn't look like that was your issue.
