When you mouseenter .li_group class it does a slide down effect on 1 single <li>
tag, everything goes smoothly, but during the delay if you take your mouse off and on .li_group it "queues" the effect and slides the li down, delay, slides it down again etc etc... I have tried every way i can think of, even stop(); but it still does it...
the reason i use mouseenter instead of hover, is because it works better for ul / li list
$(".li_group").live('mouseenter',function(){
var id = "#ec1";
$(id).slideDown();
}).live('mouseleave',function(){
if (jQuery.support.cssFloat==true || getInternetExplorerVersion() > 7) { //ie < 8 endless up/down on close
var id = "#ec1";
$(id).delay(5000).slideUp('fast');
}
});
