I think you'll be happier with the new exporter: it does this correctly I think, and if you find other problems, I'm sure Nicolas will be happy to fix them. At the risk of putting words into Bastien's mouth, I would say that at this point, the old latex exporter should probably be considered unmaintained: nobody is putting much time into it. To use the new exporter, see a post of mine from a couple of days ago: http://thread.gmane.org/gmane.emacs.orgmode/56993/focus=57007 HTH, Nick
