I have no idea.  It's the Visual Foxpro development environment.  It
could very well have been written in C++ at Microsoft.

hehe I KNOW I don't have a clue, but you didn't have to point it out :D

Wonderful.. I'll try this in a bit...

Exactly my thoughts.  My interpretation of the results, is SetCapture()
is exectuted (button down), and a SetCapture() button up is never
re-executed, maybe because of some while loop that's not being triggered
because of some weird FoxPro usage...

Well, I decided to do the relay before I sent the mail, and I do see
something.. but nothing too peculiar..

Maybe someone can get something out of that.. I've been comparing them
for the past 30 minutes and I can't see anything significant...
Interesting x11drv returns a different GetCurPos()
The 2nd Get QueueStatus after the 2nd WM_LBUTTONUP has a different
reval=00040000 on the "bad", where the "good" is reval=00060000"

I wouldn't know where to go from here, but maybe it'll help someone
else. I can run comparisons for anyone if they'd like, though I never
figured out how to save a trace to a file, > didn't work, so I'm just
scrolling now :/

Thanks for your time Lawson.
