Dropdown wont allow to select child elements

Question

At this url: http://staging.petfooddirect.com:84/ If you go over Repties. and then try to scroll on to the items, it fades out before you can select anything. I have been playing with this all morning and no results. Is it my jQuery selector?

I am using the code below in the box.

Any suggestions on what I can do?

Thank you,

Ryan

function showMenu() {
$(".openMenu").each(HideMenu); //Hide any open menus
$(this).addClass("openMenu");
$(".sub-drop-old", this.parentNode).stop().fadeIn();
$('.sub-drop-old').parent().one("mouseleave", HideMenu);
}
function HideMenu() {
$(".sub-drop-old:visible",this).stop().fadeOut("slow",function() {$(this).hide().parent(".main-menu").removeClass("openMenu")
});
}
$(function() {
var config = {
interval: 350,
over: showMenu,
out: HideMenu
};
$(".main-heading").hoverIntent(config);
