I shall have to test the header on further browsers. My other question, how to hide the title in the header while still keeping it as an element (for search engines and for the title displayed at the top of the browser), has been answered elsewhere. You add ‘display: none;’ to the h1 and .description elements in the wp-layout.css. This solution is actually given in the Kubrick FAQ:

I have got this solution to work as described in WP 1.2.2 as well as 1.5. (For WP 1.5, the stylesheet is style.css, hidden away in the themes folder.)
