Yes, that's what I mean. When unmapping the result of a SendMessage
you should do a SendMessage, when unmapping the result of a
CallWindowProc you should do a CallWindowProc (I guess, this needs to
be checked under Windows).

Do a CallWindowProc on a function that is not the current winproc of
the specified window and check if the message gets to the window.
