                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.
