Slightly off topic, but I have run into time where I wish I could lock a 
specific message or set of messages. Something like:

Lock messages for "mouseUp,mouseDown"

Generally, like so many many things in LiveCode, you can code this with 
a flag in the handlers or a bunch of alternatives. However, I still find 
myself running into this now and then.
