In RecalcFrameLayout, the method is checking to see if the "m_pFrame" member (set by calling SetSite) is a frame window. If it is not, the code gets the client rect and sends a WM_SIZE message to the m_pFrame member.

Since the client rect is obtained from the m_pFrame, sending WM_SIZE is apparently not being done to actually change the size of the window. So what is the purpose of sending the WM_SIZE message?

In case you are wondering why I care, I am trying to figure out why the popup menu that TrackPopupMenuEx (on CCommandBars) sometimes results in a failure to properly update the area under the menu once it is dismissed. Changing my Vista display settings seems to affect the update issue. Perhaps this is a "trick" to invalidate the site window? To what purpose?
