        ShowWindow() on an application frame to restore an application from
        a minimized state or a hidden state on Windows(75% of the UI test 
        automation would fail at Microsoft without this ability), it appeartly
        isn't for other platforms.  wxWidgets is or appears to be tracking window
        state internally, which leads to problems when the OS restores the window
        and the rest of the framework doesn't know about that change in state.
        Certain window events were being ignored (like WM_CLOSE, menu selection
        events, etc.). So replace the previous mechinism for bringing an existing
        instance of the BOINC Manager to the foreground by creating a new global
        window message which is tracked by the system tray icon.  When the new
        global message is fired make sure the CBOINCGUIApp::SetActiveGUI() function
        is called to restore the window state which in turn updates all the internal
        framework data structures.
