I forgot to add something. The problem is the function in the latex
hook:
 (add-hook 'LaTeX-mode-hook 'my-set-auto-capitalize) 
 (defun my-set-auto-capitalize ()
 (interactive)
         (set (make-local-variable 'auto-capitalize-predicate)
              (lambda () (not (texmathp)))))

Once it is in the hook, even removing the function from the hook does
not help anymore. I have to reset the mode. But maybe this is how the
hook is supposed to work.
