Description of problem:

1. The create new user screen in Firefox 3.0.18 displays vary narrow tables 'Available Roles' and 'Assigned Roles'. It displays the scroll bar but it is very difficult for the user to scroll or to see the available roles in the tables. The arrows to assign the roles looks misplaced.

2. Similar issue with the roles views. The tables in tabs 'Resource Groups', 'Users' and 'LDAP Groups' look compressed and so the arrow controls look placed at the bottom of these tables. 

Please refer the attached screenshots.
