        PURPOSE:  Processes messages
        
        MESSAGES:
        
        WM_COMMAND    - application menu (About dialog box)
        WM_DESTROY    - destroy window

        COMMENTS:

        To process the IDM_ABOUT message, call MakeProcInstance() to get the
        current instance address of the About() function.  Then call Dialog
        box which will create the box according to the information in your
        generic.rc file and turn control over to the About() function.  When
        it returns, free the intance address.
