This happens on any scrollbar - you can do it on the side here on the ut.

>Scroll down a VFP listbox and let the mouse cursor drift to the left of the vertical scrollbar while scrolling. The list will continue to scroll, but if you do a mouse-up with the cursor still over the box (rather then the scrollbar), VFP will select whatever item the cursor is over, even though you didn't do a mouse-down on it. I think that's a bug. Is there a workaround for it? Thanks.
