Hi Peter, Nicolas, one disadvantage of applying this patch would be that existing links to sections in HTML pages would become invalid. For the rest, I don't care. Thinking more about this, I think that people who want permanent links to sections in HTML pages will use CUSTOM_ID rather than relying on section numbers. OK, I am applying Nicolas' patch. - Carsten P.S. I think it counts as a bug in the syntax package, that it makes labels with underscore invalid. Maybe you could investigate this and submit a bug report? > > > Cheers, > Peter. > > > On 14 May 2011, at 05:50, Nick Dokos wrote: > >>> On May 12, 2011, at 9:00 AM, peter.fri...@agfa.com wrote: >>> >>>> Good afternoon all, >>>> >>>> I spent the best part of the afternoon trying to figure out why an >>>> org-generated .tex file wouldn’t compile with my set-up.
