                Check the following:
                1. Cursor must be crosshair when hovering the mouse over the
                    blue square.
                2. Crosshair cursor must not flicker.
                3. The cursor must be "I-beam" when hovering the mouse over the
                    button.
                4. Click the button - it will display "Busy" message and a
                    rotating bar for 5 seconds. The cursor must change to
                    hourglass.
                5. (Windows only) While the cursor is on the button, press Alt.
                    The cursor must change to normal shape. Pressing Alt again
                    must revert it back to I-beam.
                6. Move the mouse out of the button and back onto it. The cursor
                    must update correctly (hourglass over the button, normal
                    over the frame) even when the button displays "busy".
                    Do not try to check (1) or (5) when the button displays
                    "Busy" - this is not required.
                Pass if all the steps are as behave as described. Otherwise,
                fail this test.
