Firebug spits this out in the error console:
[Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMViewCSS.getComputedStyle]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: http://frankkoehl.com/wp-includes/js/jquery/jquery.js?ver=1.2.6 :: anonymous :: line 11" data: no]
