            if(id == 'a_link'){ var href = jQuery(this).attr("href");
                jQuery('#supersized-loader').css('display','none');
                window.open(href);
            }
        });

You should change the design of your selector a bit to prevent it handling all links:

jQuery('a[target!="_blank"]').click(function (event)

This should prevent the ajax page loader from running on links with the attribute target="_blank". The code you added inside the loader is obsolete then.

And: You can use an id only once. In your example you are using a_link at least twice.
