Just installed CWP and find one trouble. When I click on tab with submenu it starts loading all page via ajax instead just opening submenu.
Here is a fix. Just remove ajax call in this method(main.js:149). It does nothing.
 Interface will work faster:
//click magic
	mainNavLink.click(function(event) {
		$this = $(this);
		if($this.hasClass('hasUl')) {
			var menuIndexNo= $(this).parents("li").index();
			var menuAction = 0;
			event.preventDefault();
			if($this.hasClass('drop')) {
				menuAction = 0;
				$(this).siblings('ul.sub').slideUp(250).siblings().toggleClass('drop');
			} else {
				menuAction = 1;
				$(this).siblings('ul.sub').slideDown(250).siblings().toggleClass('drop');
			}	
			
/**REMOVE THIS. It does nothing! **/
			// Start :- Ajax Section
			$.ajax({
				type: "POST",
				url: "#",
				data: { menuIndexNo: menuIndexNo, menuAction: menuAction }
			}).done(function( data ) {
				//alert(data);
			});
			// End :- Ajax Section	
/** ---- **/		
		} 
	});
