When Michael says he has an 'array' of buttons, I assume he means a LOT of
buttons. Your handler will work, uh, sort of, but if there are, say, 100
buttons, it'll have to go through them all to check for a hit before it
makes its decision, so the thing'll react way slow.

He doesn't need an idle handler to poll the mouseloc, either.

I posted what should be the right solution. Check it out.
