Ok, I can't speak for the others who experienced this bug, but I found why I was. There was code (mine, not yours) which I intended to remove callbacks I had registered to OnCustomEvent, OnPrintEvent, and OnCompleteEvent. I was accidentally TOTALLY wiping them. I corrected this on my end and <PAUSE> is now behaving as it should.
I am wondering whether there is ALSO an unknown bug out there that causes the same thing to happen? Or maybe the other reports made the same mistake that I did?
