In previous version that was good but in newest still no longer work. Hover function repeats on mouseleave. This is example:

$(document).ready(function(){

$(".main-link").hover(function(){

$(this).removeClass("hovered");

$(this).addClass("hovered");

$("ul.sub-nav").hide();

$(this).siblings("ul.sub-nav").stop(false,true).fadeIn("slow");

});

});
