OK. Could you now please append the following modified version of
`scroll-bar-toolkit-scroll' to your .emacs, restart Emacs, split the
window horizontally, move the mouse into each of these windows, scroll
the mouse and tell me whether the windows mentioned in the messages you
should see (here I get for example .... #<window 3 on .emacs>) have the
same or different values.
Thanks, martin.
