The goal is to have two independent google maps each in a jQuery Tab. This will be included in a IFrame. When bounds_changed is triggered the lat/lng and zoom should be stored in a cookie. If there is a cookie available then the map should be positioned and zoomed regarding on the data of the cookie.
It seems to work with the common browsers except an actual Internet Explorer. IE does not "refresh" the map on the second tab.
