Sitename Link Bug

I found something wrong when you click the sitename link (Home link) of the Drupal 4.7 Goldengrey theme. It doesn't go back to the home page. Instead it goes somewhere else depending where you are in administering Drupal. For example, when you click administer then click modules, the sitename link (Home link) becomes http://www.example.com/admin instead of just http://www.example.com which is the home page. I've been using Drupal for a year now and I'm not good in programming but I think there's just a little problem in page.tpl.php that needs editing. Thanks again and I hope I helped.
