I need to upgrade from jQuery 1.7 to jQuery 1.8, but the backgroundPosition animation is failing after the upgrade. There are no error messages in the Firebug console at all. Has anyone else had experience with the backgroundPosition animation failing from 1.7 to 1.8?
jQuery(navSelector).hover(function(){
jQuery(this).find('a').stop().animate({"backgroundPosition":"(0 -40px)"},{duration:150});
},
function(){
jQuery(this).find('a').stop().animate({backgroundPosition:"(0 0)"}, {duration:75});
});
});
