My expandable / collapsable menu cookie for unique id is not working when I click a link on my site.

I'm using the jquery cookie plugin from github - github.com/carhartl/jquery-cookie
I have a jquery menu that grabs a unique id from the open / close buttons. When refresh after clicking any one of these, the cookie triggers the show / hide as I left it. However, when I hit a link (within the page), it either completely ignores the cookie setting and/or executes the show /hides from the previous refresh.

The cookie is being triggered in the if(_slider.length). Then the jquery for the menu is checking a.open-close, a.open-close-inner, a.open-close-inners & a.opener ids against the assigned cookie. If the cookie =  'hidden', the _activeClass is removed and the parent enclosing block remains collapsed.

jQuery(function(){
	clearInputs();
	initTabs();
	initOpenClose();
});

 
// clear inputs
function clearInputs(){
	jQuery('input:text, input:password, textarea').each(function(){
		var _el = jQuery(this);
		var _val = _el.val();
		_el.bind('focus', function(){
			if(this.value == _val) this.value = '';
		}).bind('blur', function(){
			if(this.value == '') this.value = _val;
		});
	});
};

// init tabs
function initTabs() {
	jQuery('ul.tabset').each(function(){
		var _list = jQuery(this);
		var _links = _list.find('a.tab');

		_links.each(function() {
			var _link = jQuery(this);
			var _href = _link.attr('href');
			var _tab = jQuery(_href);

			if(_link.hasClass('active')) _tab.show();
			else _tab.hide();

			_link.click(function(){
				_links.filter('.active').each(function(){
					jQuery(jQuery(this).removeClass('active').attr('href')).hide();
				});
				_link.addClass('active');
				_tab.show();
				return false;
			});
		});
	});
}

// init open close
function initOpenClose(){
	// 4 level
	jQuery('div.block-inners > ul > li').OpenClose({
		opener: '.opener',
		slider: '> div.block-slide'
	});
	// 3 level
