I have two MFC SDI applications, call them A and B. B is derived from A (B is A plus more). I put a handler for the WM_SYSCOMMAND message in CMainFrame of A and it works fine. I put the same handler in B and the OnSysCommand handler in CMainFrame never gets entered. This doesn't seem possible, and I can't think of any reason why that would be. Any ideas greatly appreciated.
