50+
This test verifies that when user switches between windows using Alt-tab
51+
key combination then appropriate window events are generated. Also, when
52+
user interacts with Menu bar, Popup menu, Choice then no excessive window
53+
event is generated.
54+
55+
After test started you will see Frame('Test for 4524015')-F1 with some
56+
components and Frame('Another frame')-F2 with no components.
57+
1. Make F1 active by clicking on it.
58+
2. Press Alt-tab.
59+
In the messqge dialog area you should see that
60+
WINDOW_DEACTIVATED, WINDOW_LOST_FOCUS event were generated.
61+
If you switched to F2 then also WINDOW_ACTIVATED, WINDOW_GAINED_FOCUS
62+
were generated.
63+
If no events were generated the test FAILED.
64+
Repeat the 2) with different circumstances.
65+
66+
3. Make F1 active by clicking on it.
67+
4. Click on Menu bar/Button 'popup'/Choice and select some item from
68+
the list shown. If any of the window events appeared in the output then
69+
the test FAILED.
