Setting the MDI client's caption

Ron, thanks for checking this out. Just a point of
clarification: you simply
downloaded, built, and ran Mr. DiLascia's Scribble app,
right? And observed
the desired behavior (i.e., parent's caption was set by your
WndProc).
Because I definitely didn't see it. I can't imagine what
there could be
about my settings / config / environment that could break
his app, so maybe
I need to wait for SP2. SP1 seems to have made a lot of
people really mad.
