Carrington Header Page Links – word wrap issue

If you take a look at my blog at https://www.bestbargaincomicbooks.com/ in IE7, you will see some of the page links at the top wrapping locally so that it looks pretty bad (take a look at Silver Age Jungle on the right). It causes a blank space and doesn’t look good at all. If you take a look at the same blog in Firefox, it looks great.

Any help in resolving this issue is very much appreciated. Thanks in advance, William
