Hi, Tassilo, Thanks for your reply. I have updated the emacs to 24.5.1, and installed auctex 11.88.8 by `package-list-packages'. however, the problem seems still exist: when `C-M-@' (mark-sexp) at the beginning of a `\begin{...', only `\begin' canbe marked, instead of the whole env. And also the `forward/backward-sexp' can only effect to the `\begin'.
Would you have any other suggestions?
