WAIT WINDOW NOWAIT "moving item..."Perhaps you don't see it becuase the mouse is moving. With the NOWAIT clause, a mouse move will clear it. Since the mouse is moving to move the item which triggers the WAIT WINDOW, the mouse moving also clears the WAIT WINDOW, hence you don't see it. In the other example (that you say works for you) there is no NOWAIT clause so the WAIT WINDOW persists and you see it.
