In another thread ( http://forum.jquery.com/topic/queueing-up-animations) there's a discussion about a fairly simply animation.  It works fine in IE8, and in recent versions of Firefox, Opera, Safari, and Chrome.  But it is pretty haywire in IE6 and IE7.  I'm afraid I don't know nearly what I should about browser quirks.  Can anyone suggest a reason, or even better, a fix?  A sample of the animation is at


Thanks,
