Dear ESS developers, I work with ESS 12.09-1 (2012-12-21) (under Ubuntu 12.10 with Emacs 24). If I use C-c C-n to linewise step through an R script and if I end up on the last line of the script (but continue to use C-c C-n), then this line is executed again and again... is this a bug or a feature? Cheers, Marius
