+                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.
