--- Comment #8 from Ben Klein shacklein@gmail.com 2008-01-06 18:54:54 --- What I think is going on here is that DragDetect is dropping the WM_LBUTTONDOWN message from the queue before it gets sent to the application. MSDN seems to indicate that DragDetect waits for WM_LBUTTONUP, mouse motion, ESC key press, or moving outside a specific rectangle, and doesn't return until one of these things happens. Wine's implementation uses PeekMessageW with the PM_REMOVE flag, so the message queue is consumed.
