Noticed here on your site: When I'm logged out of the forum and try to use one of the tools-menus on forumdisplay or showthread, the dropdowns just open for as long as I hover over the link, but close immediately upon leaving -> I cant choose menu entry or search a forum/thread. Happens to me with FF 3.6.3, works in IE 8.

// Hm, funny, now they do. Addendum: I realized the tweets-addition on the left do a little jump when I had the problem.
