Title used for pages
In the template.php of the theme add the following code.

function phptemplate_preprocess_page(&amp;$vars) {
  $title = $vars['title'];
  $site_name = $vars['site_name'];

  $vars['head_title'] = implode(' - ', array($site_name, $title));
}


Verify the $head_title variable is present in page.tpl.php.
