Text Causes Sidebar To Appear At The Bottom :(

When I make a link like in this picture:

It goes outside of the box in firefox.
and if I view the site in internet explorer it causes the box to become wider and that causes the side bar to appear at the bottom of the page.

Is there something I can insert in the css to make that link wrap around.

I dont want to hyperlink to something such as go here.
