I have some user scripts depending on jQuery.
They usually works well, but now, after I switched to a new OS (I'm not sure whether there're any connections), they cannot work well on action=edit pages (and only edit). After leaving beta, nothing goes wrong.
In nutshell, the wrong behavior is, jQuery cannot always select correct elements in DOM tree.
