Lock screen challenge

[Ralph DiMola]

Not to be Johnny Rain Cloud... What if handler "A" locks and it calls either hander "B" OR handler "C" to unlock?

Thanks to both you and Craig. I couldn't think of any other way to do it either, but was hoping there was something other than brute force. Magic, maybe. It took LC's search/replace dialog a long time just to find all the instances, and actually editing them will be longer. But, it's just a one-off.

Craig, I posted here because I more comfortable with it, and because more old-timers tend to be on the list.
