Hi Robert,

thanks for your response.

I run multiple instances of emacs simultaneously, one of them
specifically for email, i.e. gnus, and that emacs instance was running a
previous version of org...  the tests were done with the latest version
(-252-).  sorry for the confusion.

I went through that thread and I'm not entirely sure if or how it
relates to my issue.  However, I tried going back to June (well before
the patch mentioned) and that version shows the same behaviour I am
seeing now but worse (more lines changing from one export to the next)
so maybe it is related.

Actually, my settings are at the end of the whole 4000+ line file so I
am not sure what you are suggesting I try.  If I delete the whole
settings subtree, the exports all result in the same LaTeX.  However,
that is of no use to me, obviously.  I guess I can try to add one line
at a time to see when the export breaks.  I may try that tomorrow.

I guess I would like some insight into how the latex_header lines are
parsed by org, maybe in org-element?  There is something strange going
on because every or most evaluations of the export dispatcher to LaTeX
lead to slightly different results.

Thanks again,
eric
