Unless you got a "No Java Script" error message above, you should be free of the frame now!
I wish I could take credit for this little bit of Java Script, but I can't.  I ran across it at http://www.ziskadesigns.co.uk/pethates.html.  According to that page, the code was written by Alan Simpson at www.coolnerds.com, however I get a Page Not Found error when I try to go to it.,
