I've only been using it with IE. I tried with Opera, but it complained too much, and I later found out that pac files were only partially supported at the time (may have changed by now). It was primarily written for Netscape though. I even tried uploading it to a web server to see if it was an issue with the file:// url... doesn't seem to be. I've been using the one found here.

I modified it a bit, but nothing terrible.
Wow - is there a problem with the form, or is K-m not painting it right? The text disappearing. Hope it posts right.
