Wow, that's a REALLY old version of ACE. I recommend that you upgrade
to ACE+TAO x.4.7, which you can download from

http://deuce.doc.wustl.edu/Download.html

under the heading "latest beta kit".

I think Windows stores the windows information in thread-specific
storage, so you need to make sure that the thread you use t initialize
the window is the same one you use to process of messages.
