I don't remember getting it.

I recall having this problem... I don't rememeber exactly how I resolved it.
Try setting up your window and showing it using ShowWindow() or something.
Maybe messages are sent only once the window is created and shown. This
would explain the MessageBox() thingy making it start working.
