I was describing what the code is supposed to do, and what it currently does on my system. I am not quite sure of the reason why it doesn't work on your system. Is the config the following? (add-hook 'LaTeX-mode-hook (lambda () (add-hook 'after-change-functions #'preview-point-buf-change nil t))) Note the hook name `LaTeX-mode-hook`, not `LaTeX-mode` as I mistakenly had in the very first version of the package (in case you copied it from then). If so, I might be able to pin down the reason if you check the following: - What is the value of `major-mode` in your document? - Are there any messages in "Messages" after editing the code. - Is the outdated preview greyed out? - After editing the equation, if you call preview-at-point, is the preview updated? - After editing the equation, if you press: M-x (preview-point--preview-at-point (point) (current-buffer)) is the preview updated?
