           This test verifies that when user switches between windows using Alt-tab
           key combination then appropriate window events are generated. Also, when
           user interacts with Menu bar, Popup menu, Choice then no excessive window
           event is generated.

           After test started you will see Frame('Test for 4524015')-F1 with some
           components and Frame('Another frame')-F2 with no components.
           1. Make F1 active by clicking on it.
           2. Press Alt-tab.
           In the messqge dialog area you should see that
           WINDOW_DEACTIVATED, WINDOW_LOST_FOCUS event were generated.
           If you switched to F2 then also WINDOW_ACTIVATED, WINDOW_GAINED_FOCUS
           were generated.
           If no events were generated the test FAILED.
           Repeat the 2) with different circumstances.

           3. Make F1 active by clicking on it.
           4. Click on Menu bar/Button 'popup'/Choice and select some item from
           the list shown. If any of the window events appeared in the output then
           the test FAILED.
