TypeError: toggleTrigger is null 	  toggleTrigger.innerHTML = "◄";

Firebug show this error on this function:

``` js
        self.show = function() {
            slide(0);

            toggleTrigger.innerHTML = "◄";
            toggleTrigger.setAttribute("title", "Hide Toolbar");
            hidden = false;

            cookie.set(cookieKeyHidden, 0);
        };
```

and there is no icon to close toolbar
