            1. Keep the instruction dialog and TestFrame side by side so that
               you can read the instructions while doing the test
            2. Click on the 'Start Busy' button on the frame titled 'TestFrame'
               and DO NOT MOVE THE MOUSE ANYWHERE till you complete the steps below
            3. The cursor on the TestFrame changes to busy cursor
            4. If you don't see the busy cursor press 'Fail' after
               the `done sleeping` message
            5. If the busy cursor is seen, after 5 seconds the message
               'done sleeping' is displayed in the message window
            6. Check for the cursor type after the display of 'done sleeping'
            7. If the cursor on the TestFrame has changed back to default cursor
               (without you touching or moving the mouse), then press 'Pass'
               else if the frame still shows the busy cursor press 'Fail'
