Hi there Derek,

Now that i see it written out it doesnt seem as bad as it originally
looked.  Just one question...did you have a problem with using
GetWindowLong() with GWL_USERDATA that would motivate you to look
for another method of managing id's ?


Take care,
Al

And, good luck with your Euphoria programming!
