Hi, As part of my LaTeX-math-list I redefine ` M-+ to something. It would seem that XEmacs translates ?\M-+ to one-character "<<" the french use for quotes. Next time I use customize, this messes up the parentheses count completely, resulting in something that looks like one custom.el file and a half... afterwards, xemacs doesn't really want to go up properly, and I can't really blame it. I use xemacs 2.4.6, auctex 1.29, xemqacs-base 1.58, textools 1.12 (anything else I shouldlist?) Any suggestions, please? If so, CC me, as I am not subscribed to this list. Thanks, Itay p.s. I attached my custom.el file, as pine did not want to accept these 8-bits character inline.
