Forum Moderators: not2easy
if you still have the default drupal.css being called you need to explicitly override some (or all might be better) the defaults for the primary tabs ul and li elements.
you should not need to modify any template files once the default CSS is neutralised you can style the list as you like
but if you like it is not hard to mod the template just paste the entire primary links list into the header template file and then absolutely position it
