Since the layout uses "http://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js",                             "http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.3/jquery-ui.min.js", I'm guessing that the features you want to use are not available in this version. I've been burned in the past by having two versions of jquery loaded on the same page. Maybe they've worked that out. Do you think it is safe to upgrade for the entire application?
