I have a problem in org-version 7.9.2 (from emacs-snapshot): if I set org-agenda-span to custom 14 (not day, week, month or year) than the function org-agenda-earlier doesn't go back anymore, it goes forward instead of. If I switch the view by org-agenda-week-view or org-agenda-day-view, the function org-agenda-earlier goes back as expected. In think this is a bug (by the way it works fine in org-version 7.8.11)?
