In order to have working comments I've switched to a completely new template. The comments line now pops up without having to jump on it before it disappears, but I haven't yet figured out how to retrieve the old comments. Anyway, the new template is cleaner, and looks a lot better on Firefox. I'm now trying to contact JS-Kit to see where the old comments are hidden. If you click on 'Comments', a 'Leave a comment' line appears, which, when clicked on, leads to the comment box. Still no spellcheck.
