As Bastien indicates this is a known problem, I will assume there is an existing bug report and won't create a new one. I will post my results back here. Given the combinations to test, this will take some work and some time. One question I do have, how do I run emacs bzr trunk with org 7.4? Is it sufficient to just ensure some 7.4 load directory is first in the load path? Also, what is the url to get 7.4? Tim
