Note that due to histe^Horical reasons, win32ui is a wrapper around MFC (a
more object-oriented framework), whereas win32gui is a very raw wrapper
around the GUI related API functions.

It "should work" :)  By using win32ui, you are including all the MFC
framework, which can get in the way.  win32gui generally has less
side-effects, but may still impact when embedded with other GUI frameworks
that make their own assumptions.

If you are using win32gui rather than win32ui, then ensure you have build
201 installed - an obscure win32gui hang was fixed in that build.

But otherwise, unfortunately, and as usual, the best answer is to reduce the
problem down to the smallest possible sample code that demonstrates the
problem.

That should be quite simple, and a reference to vb2py has already been made.
Note however that "message loop for callbacks" is still fairly low-level -
you are dealing with the various Windows messages, which really can't be
considered a friendly callback framework.  I *still* can't believe how hard
GUIs are, even with a decent framework; a conceptual leap is waiting to
happen here, IMO.
