It's taken me ages to find out why my window, built out of win32all, wasn't
receiving any messages. Eventually I found the answer here:

http://mail.python.org/pipermail/pyt...er/069451.html

The important point being:
> IIRC you have to pass the return value of the RegisterClass() call (which

.... in other words, you can pass the name of your window class as the second
parameter, but it will silently fail to work. (This holds for CreateWindow
too.)

This is a bug for which it is pretty much impossible to work out the
workaround without being told it, so I'd like to put the workaround in a
more easily-found place. But where? win32all doesn't seem to have much
documentation, much less a bug database.

In case anyone else needs to find this message by searching, some keywords
are: win32all, win32gui, WNDCLASS, RegisterClass, CreateWindow,
CreateWindowEx

Win32all is called Pywin32 now, and resides on SourceForge:
http://sourceforge.net/projects/pywin32/
