Clash between new JQuery UI and quickmenu.js

Clash between new JQuery UI and quickmenu.js


I'm pretty new at javascript and JQuery but have to say that JQuery is
simply amazing. My problem is not with JQuery UI, as it works
seamlessly but rather with quickmenu.js. Quickmenu worked very nicely
until I started using UI on the same page and it now gives me the
following error:
jQuery(this).children("div").attr("onclick") is undefined
jQuery(this).AddBreadcrumbs(jQuery(this...r('onclick').toString().split
('\'')[3]);
I'm really stuck. Any help would be greatly appreciated.
thanks in advance.
