[ESS-bugs] select-window (C-c M-j) doesn't give input focus to target (*R*) [Carbon GNU Emacs]

[Stephen Eglen]

Thanks for the report David; it sounds like a problem with the recent
change in Emacs CVS.  I run CVS Emacs, but am a few months behind, so
that bug has not bit here yet.  I will investigate (as I looked at
cleaning this code up a year or so ago), but not likely for a couple
of weeks.
