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.
