You're right. I should have thought of that.

I'm sorry, but I've since rebooted, so I no longer have that session (and I
can't reproduce that part of the problem).

Again, though, it would still be good to have the entire (small) space under
the vertical scroll bar as drag handle (even for the rightmost window), for
the reasons I mentioned. And there is no reason that the mode line should
seem to be selected or become active, just because you use the drag handle.
IOW, the Emacs 20 behavior is preferable in terms of usability: more
intuitive, more visible feedback (visible affordance), and an easier handle
to grab.

    Here's the backtrace (although it's not very helpful):
    Debugger entered--Lisp error: (error "Attempt to drag leftmost
scrollbar")
      signal(error ("Attempt to drag leftmost scrollbar"))
      error("Attempt to drag leftmost scrollbar")
      mouse-drag-vertical-line((down-mouse-1 (#<window 3 on *Help*>
    vertical-line (300 . 344) 7448410 nil 342 (0 . 8) nil (0 . 215) (1 .
16))))
      call-interactively(mouse-drag-vertical-line)

What happens if you install an interpreted version of
mouse-drag-vertical-line in that session?  Does the bug still happen?
If so, you can get some real info from the backtrace when
it is running interpreted.
