Lock screen challenge

[J. Landman Gay]

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.
