On my system (OS X) the buffer does not popup. I just tried #+BEGIN_SRC sh echo foo 1>&2 #+END_SRC in Aquamacs and Cocoa Emacs. Strangely, the output seems to be lost entirely.

Okay, thanks. My elisp skills are very rudimentary and this is beyond me. Maybe somebody else will pick it up if the interest is big enough. Cheers, Viktor
