However, this is the most complicated code I've ever seen (needless lots of objects, just to make it obscure). The only thing I'm reasonably certain about is that the secret is in http://www.timeinc.net/subs/popup2/fortune/popup2.js especially in the function test(). However, this just refers to a new heap of objects and I don't have more time to do research. If you do find out, please let me know. >Any ideas?

If they leave your site your ASP won't be called so it can't do anything. ppk _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
