Not sure anyone has run into this problem. I searched the forum and couldn't find anything. I have Shadowbox 22.214.171.124 running and in IE 8 it give me a error
J.parentNode is null or not an object
then the url - /wpmu/wp-includes/js/swfobject.js?ver=2.1
If I disable it it goes away.
I don't have this problem in Firefox.
