ok.  Have you gone through the logic in ess-show-buffer?  IN
particular, see part 2:

      ;; 2. Maybe BUF visible in another frame.
      (setq frame (ess-buffer-visible-other-frame buf))
      (if frame
	  ;; BUF is visible in frame, so just check frame is raised.
	  (if (not (eq (frame-visible-p frame) t))
	      ;; frame is not yet visible, so raise it.
	      (raise-frame frame))

I'm not able to test this right now, but my memory the other day was
that the code at the end of ess-show-buffer was able to select-frame
and then put the mouse in that frame to make the frame active.  I
wonder if that is the problem?  (Maybe there is an interaction with
the O/s here, with mac requiring click of the window to grab the
focus?

Can I clarify?  If the frame containing *R* is currently split to show
more than one window, you do not see the bug?

Okay.  That makes sense.
