When you go into the admin panel, you are opening up a new "_parent" link which opens a frameset.
As we can see with your frameset waaay too much space is allocated to the Admin Panels frame.
Two ways round it are 1) use a browser that will allow you to resize the frame - then you can drag the divide back to a more reasonable location.
Edit an as yet unknown file to change the frame settings. (I am not sure which).
Or is it related to the way lycos is delivering your pages???
