Same here. Anytime I want to lock the screen, I do this:
on lockTheScreen
if not the lockScreen then
lock screen
end if
end lockTheScreen
When needed, I use this:
on unLockTheScreen
repeat until not lockScreen
unlock screen
end repeat
end unLockTheScreen
That's my 2 cents.

When I have a handler that needs to lock the screen I will often do the
following
begins handler
put the lockScreen into tPreserveLockScreen
if not tPreserveLockScreen then lock screen

code
...
if not tPreserveLockScreen then unlock screen
end handler
Code in our main LC app is large enough that there are instances where
the some code that calls the handler needs to lock the screen and other
code that call it does not, but the handler always wants to hide changed
until done.
