Hi again Derek,

I had considered using Windows Properties API's but decided that because
they use string values that they would add an unnecessary delay to
looking up the id's, and using ATOM's would muddie up the processing
and probably cause a delay also.
I still like your hashing idea and may turn to that at some point
down the road, unless switching to using GetWindowLong exclusively
works the way i want it too :)


Take care,
Al

And, good luck with your Euphoria programming!
