Thanks for the reply, I appreciate your expertise and hope you can get
me out of this deadlock.

No inter-thread SendMessage whatsoever. This is all stuff I've done
successfully in the past, at 6.0, and I can't seem to make it work
now.

My main thread creates a CWinThread-derrived class with AfxBeginThread.
That thread creates a modeless dialog in InitInistance. Things are fine
until the main thread enters a loop iinside a message handler (the
reason for the progress thread. The loop has a generous Sleep() in it
so it's not hogging the CPU. After that, the modeless dialog in the
'progress' thread is dead. Spy++ shows it never gets any messages. If I
break into the debugger I see my progress thread blocked at a
DefWndProc call to m_pfnSuper. And it's total fog to me after that
point, as I don't know what m_pfnSuper represents. I suspect MFC is
trying to pass unhandled messages to the main window, thinking it's the
parent of my dialog, but that makes no real sense. When I create the
modeless dialog I don't give it a parent.
