[ESS] hitting return won't move the cursor down

Hi,
what version of emacs are you using (M-x emacs-version)

Also, follow the next steps to help us debug:

----------------------------------------------------------------------
   If Emacs reports an error, backtraces can help us debug the problem.
Type "M-x set-variable RET debug-on-error RET t RET".  Then run the
command that causes the error and you should see a *Backtrace* buffer
containing debug information; send us that buffer.
