jquery accordion help

I have a horizontal accordion on my website, and regardless of wha开发者_如何转开发t page you on the tab furthest right does not act like the rest, you click the tab and no accordion action happens, I am not sure if this is IE all versions problem or just an IE9 problem, but if someone could spread some light on it that would be great. As I have been looking for bugs for 2 days now and cannot find anything wrong.

Works fine in IE7 and IE9, IE8 doesn't seem to work at all though for clicking (still cycles through). FF6 works too. Haven't checked anythign else. You sure its not a cache issue? If you made any recent changes, make sure that you are getting the most up to date files.

EDIT:

IE8 only works when clicking the top portion. 38px high.

It worked very well in IE8.

It works quite well in Chrome 13.0.782.215 too.

You've got a great looking site!!! Very well done.
