Nav Menu Wacky in Safari weird links in comments

https://www.thevitaminstringquartet.com/blog/2009/06/vitamin-string-quartet-giveaway-radiohead-cat-power-no-age-etc

The few navigation buttons at the top look fine in FF and IE but not in Safari. Any ideas on how I can fix that?

Also, there is a link in one of the comments that goes outside of the comments area instead of returning like the rest. Any ideas?

Thanks
