+            This test checks that focus is transferred properly back
+            to top-level after clicking on a tray icon.
+
+            When the test starts, a Frame with a text area & a RED tray icon
+            are shown. If you don't see a tray icon please make sure that
+            the tray area (also called Taskbar Status Area on MS Windows
+            Notification Area on Gnome or System Tray on KDE) is visible.
+
+            Click with a mouse inside a text area and make sure that it has
+            received input focus. Then click on the tray icon and then back
+            on the text area and verify that it has input focus again. Repeat
+            the last step several times. Ensure that the text area always
+            has the input focus and there are no "FOCUS LOST" event
+            for text area in the log section.
+
+            If above is true, Press PASS, else FAIL.
