I seem to be getting an error when browsing my site using Internet Explorer.
I get a popup displaying "Stack overflow at line: 154".
Works fine on Chrome, Firefox and Opera. Opera's Dragonfly produces the following information:

Uncaught exception: RangeError: Maximum recursion depth exceeded
Error thrown at line 154, column 8066 in (g, f, i, h) in http://www.mywebsite.net/test/sites/all/modules/jquery_ui/jquery.ui/js/j...
return f?d.effects.animateClass.apply(this,[{add:g},f,i,h]):this._addClass(g)

The only information I can find that might be relevant says "any recursion that happens through the window object is limited to a stack depth of 12"... Which I can honestly say I do not understand...

Is anyone able to shed any light on this issue? Is it a problem with my website or this module specifically?
