Dear All, after admittedly erratic search for an answer, may I finally ask, how to avoid the search for R versions at start up of ESS 12.04. Until now I used ess 5.3.3 and with the line (setq inferior-R-program-name "d:/rw/bin/r.exe") in my .emacs all worked well. Can I use ESS 12.04 without the search for R versions? best regards, Heinz
