Hi Vangelis,
I've come up with a solution, which is to customise the mode the
export buffer is opened with. You could set it to plain latex-mode
instead of LaTeX-mode. This will disable auctex functionality. Would
that be an issue for you? I don't see any specific advantage in having
the auctex functionality enabled on a *read-only* buffer, but that's
also, just maybe, because I have never used it...
If you are interested, I could share a patch for the all-tex-fonts
feature branch.
Speaking of which... I have been trying to reproduce the problem on a
clean emacs (master) with auctex/reftex from elpa and the feature
branch and was not able.
Could you share a bare minimum init.el file I could use to reproduce?
Best, /PA
