Don't know if this is been addressed here, yet, but I discovered a really tedious syntax issue with IE and the css() method in JQuery. Basically, this error never comes up in Firefox or any Mozilla-based browser for that matter, but in IE JavaScripts will fail when you do:
$('div').css({class: 'my-class-name'}); You simply need to make sure that class is enclosed in quotes $('div').css({'class': 'my-class-name'}); I would guess that IE reserves "class" in javascript, so it just bombs out when included in an object.
