Admin bar and "normal" wp theme


I am offering a "normal" wordpress theme for blogs on my WPMU /buddypress installation...

On this "normal" theme the adminbar covers parts of the header - not only on the blogpages, but also on the admin-dashboard of that blog.

Is there any easy way to adjust this?

Nice Greetings,


Here you see my main frontpage - everything OK.

And this is one of the MU Blogs with the "normal" theme, top covered with the adminbar.

The dashboard, covered too.

I BET there is an easy way solve this...
