Here's one way: add the following lines to your .emacs. As long as the
defadvice comes after you've loaded ess I think it should work.

;; ESS - the load line should already be in your .emacs:
(load "/home/tyler/dl_src/emacs22/ess-svn/lisp/ess-site.el")

(defadvice ess-eval-region (after unmark-after-eval)
  "Deactivate mark after sending region to the ESS process"

(ad-activate 'ess-eval-region)  

This appears to work on my setup, and should be robust to moderate
changes to the ess code.

Don't know. I haven't had this problem, but my preferences may be a
little peculiar. I'll leave it in my .emacs for a while and see if it
makes me a happier or more productive person ;)



"Primroses and landscapes have one great defect: they are gratuitous. A love 
of nature keeps no factories busy... We condition the masses to hate the 
country but simlutaneously we condition them to love all country sports. At 
the same time, we see to it that all country sports shall entail the use of 
elaborate apparatus. So that they consume manufactured articles as well as 
transport. Hence those electric shocks."
