Sometimes, in firefox 2.0.0.6 on Windows XP, after mousing over all the links in the top of the page (Home/Edit Page/New Page/Comments/Files) a few times, the "edit page" link then becomes unclickable. Please make the edit page degrade gracefully or something, so that it's always able to be clicked, sometimes the javascript is making it unclickable, which is annoying and will confuse the other people who are just starting to use my wiki.

This occurs in the Hyperreal skin and the Bamboo skin, and I've also seen it happen once so far in the default "snakeskin" skin. It may be related to a lot of javascript activity prior to the mouseover failing, though I couldn't say.
