Popup killer problem (Zone Alarm)

[Mythril]

I have a PHP script that calls itself (I'm not sure if that matters) through form submission, and it works fine if I have my popup killer turned off. However, once I turn it on, every time I submit the page, it ends up running the script twice, which is really annoying because it does database calls. I've also noticed this problem occuring with PHPBB. Any idea on how to fix this? Thanks.

Hmm... that makes no sense. I don't understand why it would run it twice, let alone do anything, since it's not a popup. Have you tried it with a different popup killer?

I haven't, but my friend uses Popup Killa, and the same problem occurs.
