Someone else asked about this on the list a while ago. I've had this in
my .emacs since then, and it seems to fix the issue, although perhaps
not optimally:

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

(ad-activate 'ess-eval-region)  

I think it might be better to add (deactivate-mark) in the body of
ess-eval-region, but maybe there's a good reason not to.

Cheers,

Tyler
