is lock cursor of any use whatsoever?

I'm confused. If you want the cursor to stay invisible when the handler 
quits then you merely have to say,

on mouseUp
    set the cursor to none
    lock cursor
end mouseUp

And you can get rid of that distracting pointer. :)

If your goal is a handler that never exits then I imagine,

on mouseUp
    set the allowInterrupts to false
    repeat forever
    end repeat
end mouseUp

will work. Although I suppose it still doesn't satisfy "never" since a power 
interruption, force quit, or restart will stop it, though certainly not 
gracefully. Why would you not want handlers to exit?
