Hi Rainer,
Thanks for your patience and persistence. I've pushed up what I believe
should be a fix for this excess buffer movement. There still may be
some issues with things like ess-load-file, but those can now optionally
be squashed by wrapping your hook functions with `save-window-excursion'
as shown.
#+begin_src emacs-lisp :results silent :tangle no
(add-hook 'org-babel-post-tangle-hook
(lambda () (save-window-excursion
(ess-load-file (buffer-file-name)))))
#+end_src
Best -- Eric
