--- Comment #9 from Rein Klazes wijn@online.nl 2009-03-26 04:24:21 --- I can see the bug allright. It doesn't happen with 100% repeatability but after some mouse clicking/dragging the scroll bar in any way it stops functioning.
The reason is getting clear as well: after the WM_LBUTTONDOWN message, the app sends first a WM_CANCEL message, followed by a new WM_LBUTTONDOWN message. The first message should ( I suppose) cancel the scrollbar tracking, and the second start it anew. Wine does not cancel this tracking, which leads to multiple lines of execution tracking the scrollbar and not enough WM_LBUTTONUP messages to finish them all.
