Druapl Panel Page - CSS work

We have a user profile panel page in a Drupal site that when the user goes to edit the content the fields on the edit page 'spill over' the right side margins of the page. Should be an easy fix. Note - the page in question contains cck multi-group fields. If you are not familiar with these types of fields they allow the user to add additional groups of values when adding/editing. The user profile edit page utilizes vertical tabs. Along the left hand side are a series of tabs, (see image A). Each tab contains fields that the user fills in with their info. Their are four tabs that contain cck multi-group fields that are spilling over on the right hand side- (see images: Career Summary, Areas of Specialisation, Programs & Workshops and Products). Note that image A is correctly formatted and the fields do not spill over. The site employs a custom theme, so we would like you to put the changes at the bottom of the css file under the custom theme. There will be additional work to help with the clean-up, so prove your skills here and you'll get more work.
