+                1. A Frame should appear with a "test" button in it
+                2. Click on the "test" button. A Dialog will appear with a "dismiss" button
+                   and a "dismiss-with-dispose" button
+                3. First, click on the "dismiss-with-dispose" button. Verify that
+                   no assertion failure appears.
+                4. Now, click on the "dismiss" button. The Dialog should go away.
+                5. Repeat from (2) 10-20 times.
+                6. When the dialog goes away check that the frame window does not briefly
+                   get obscured by another app or repaint it's entire area. There should be
+                   no flicker at all in areas obscured by the dialog. (4065506 4122094)
+                   If there is the test fails.
+                7. If the Dialog is successfully hidden each time, the test passed.  If the
+                   Dialog did not hide, the test failed (4048664).
+
+                NOTE: When the dialog does not go away (meaning the bug has manifested itself),
+                the "dismiss-with-dispose" button can be used to get rid of it.
