google analytics for wordpress mu causes theme preview screen to go blank on 3.0

I use a mac so most of the time I browse with safari. I had recently gotten my google analytics codes from the google site. I inserted them into the field as required. I had been installing & previewing themes for my wordpress mu site because I was trying to see what kind of look that i wanted to have but today when i went to preview themes. They would not work. I searched google for every possible solution until i decided to try & pull up the site using firefox. Firefox allowed me to find the problem. It showed the process of the screen transitioning to the preview & then suddenly going blank....meanwhile the status bar showed that it was trying to connect to google analytics. I decided to remove my google analytics codes & BINGO!!! preview is working. I hope you guys fix this because i need it to
