Active link doesn't refresh on refresh

Hi,

I'm just working on a redesign for a site and I can't get the active link to refresh back to its default colour.

See http://www.felix.peacefriend.com/tindex.html to see what I mean. I'm talking about the 5 main links in the middle of the page. If I refresh the page, the last active link stays highlighted unless I click another link.

I presume I can just add an onload command to click it away when the page re-loads, but I can't work out why it happened in the first place.

(The rest of the site is not finished yet, so it's possible I need to tighten up the HTML).

Thanks.
