Scroll bar persists in tribes

[ecurrencyhodler]

The scroll bar which (I think) should be displayed only in the friends bar is also displayed in the tribes column. Not only that, it persists when I scroll up and down. We should remove that when I'm scrolling up and down and looking at various tribes.
