title: scroll tabs in flex 3
body: <p>I need to make a tab navigator in flex3. If no. of tabs increases then i need to show scrollbar to navigate over the tabs. I am trying to do this using tabBar. But if no. of tab increases it puts scrollbar around the parent of tabBar and its content. Whereas i need to scroll only tabs not its content like in firefox. 
  Could anybody please suggest me how could i accomplish this.</p>
