In case you are not aware, OA Premium in banking mode allows connections to certain other web sites than your specified domains. So when you are connected to your bank, your browser can still open connections to Microsoft, Sun etc. Details here: http://support.emsisoft.com/topic/7576-banking-mode/page__view__findpost__p__46193 So if you want a complete locked down browser except only one connection to your bank or shopping site, you have to stop the ones above through a Hosts file or other software. Hope this is useful and has not been posted before. Thanks Edit: The above list is hard coded in OA Premium and cannot be overridden in OA banking mode.
