0.8.5 WP UI does not work with WordPress 3.5

@signcarver just an FYI your FAQ page is not rendering an accordion in IE.

usually because some value has not been defined or set, it usually likes everything to be declared. But the issue with this plugin has to do with the below function throwing this error:

Unable to get value of the property ‘ajaxClass’: object is null or undefined
script block (14), line 40 character 6:

Any help would be great!

Found the problem, it conflicts with Widgetkit by Yootheme. I assume they are both loading Jquery, that is usually the problem.

WP UI breaks all my accordion menus in the WP backend. As far as I can say, it’s since the 3.5 update. I can only deactivate the plugin to get the backend menus working again. I tried all solutions, mentioned above. Anyone else with this issue?
