Well it works and I am not clear in what you did. My site is still open, I can visit it so it must be some odd browser error. It works fine for about 150 people a day so I assume you use some odd browser popup killer. There is a javascript (from tripod) in there, that shows some annoying header. Acording to the stats I see it works with firefox, msie, netscape and opera so I dont know what your settings are. Join the forum at
