How to remove border around radio buttons in IE7

Hi, when creating a form using the Form Wizard and using the standard chronoforms stylesheets I get a border around selected radio buttons in Internet Explorer 7. It doesn't appear on a Mac or Firefox on a PC, just IE. Could anyone point me to where these buttons are styled in the CSS so I can have a go at fixing this.

Hi joomlajc.

Get FireBug in Firefox (or Chrome, or DeBugBar for IE) and take a look - could be many places.
