The function should be a member of CWnd-derived class; I've heard that VC7 uses static_cast instead of old-style casting, your code may not compile under VC7.

3) There's a topic called "Message Categories" in VC help that explicitly says that non-CWnd objects derived from CCmdTarget can't handle messages other than WM_COMMAND. My understanding was that only WM_COMMAND is routed to document and app, but your experience denies that. I'd really like to see who's calling CYourDoc::OnMessage :-D
