I have now looked into this bug, and this time think that I've fixed
it.  If some kind soul could test it out, I'd appreciate it!  Please
download the new version of ess-inf.el from

[ESS core: it is now in CVS]

If you have the following in your .emacs, then comment it out (put ;;
at the start of the line or delete it):
  (setq comint-scroll-to-bottom-on-output t)

Then re-run Emacs and R.  Try sending a few lines from an .R buffer to
*R* using C-c C-n and hopefully this time the cursor in the *R* buffer
will stay at the end of the *R* buffer.
