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.
