I can't find where in MFC the individual View/Document/Frame names are added to the "Window" menu.
CMDIFrameWndEx::GetWindowMenuPopup searches the top level Menu for ID_'s related to the "Windows" menu. and returns this sub menu. But it doesn't modify anything.
I guess I could override this function to return my own HMENU that I handle directly. But I really, would like to know which function in MFC adds the items to this "Window" menu.
