JQuery UI tabs crashing in IE7

JQuery UI tabs crashing in IE7

Hi,

I am trying to fix a problem on the following website http://mvc.whclpreview.com/ToolSelect

When a user clicks on the i on one of the coloured tabs a popup of a set of UI tabs appear.

All is working fine on all browsers but on IE7 the website is crashing the page.

Can anyone help please?

Thanks.
