Hi Hendrik,

I can't reproduce what you're describing.  It looks like this for me:

[x.png (image/png, inline)]

[Message part 3 (text/plain, inline)]

Can't reproduce that either.  Typing "\left(" completes to
"\left(\right)" for me.

Can you please start Emacs with

    emacs -Q &

and in scratch buffer, eval these lines:

    (require 'package)
    (package-initialize)

open your .tex file and see if happens again?

Best, Arash
