I have just notice that the column width over set in the file style-artisteer-overrides.css doesn't apear to follow through in IE (ver 8 - Vista)

Works fine in Firefox. In addition, the text box used in a newsletter subscribe box overhangs the edge of the main page when the instance is placed in the right column, if viewed in IE Tab within Firefox, although it doesn't when viewed in IE 8 or Firefox on there own.
