It is part of the mac user interface guidelines not to update the screen during scrolling when the "thumb" is being moved, only to update when the arrows are clicked. From the point of view of programming it in a new application, it is extermely easy to do. But adding it to existing applications would require rewriting the scrollbar control routine.
