>>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.

I don't think I understand what you're saying. The mouse-down event is what initiates the scrolling action (mouse down on scroll thumb, then drag). It's when you accidently let the cursor slide to the left of the scrollbar when scrolling, and THEN mouse-up, that the listbox item is inappropriately picked. This can screw things up after you've ctrl-clicked several ad-hoc items and now you're simply scrolling to another section of the list to continue selecting more items.
