Facebook icon links to homepage when logged out

Hi there,

Here's an odd sort of thing--when logged into wp-admin, clicking on the Facebook icon in the header goes to to the correct link--Facebook.

But, when not logged in, clicking on the FB icon just opens up in a new tab the homepage. weird. Thanks in advance for your help.

Ha ha...never mind, it seems to be a caching thing--weird that it did the same thing for two different people, but seems fine..
