What is it you're talking about that's in the code, exactly? I'm looking through it, and not seeing anything unusual. I had a similar problem before on both of my message boards that I run, one just recently...but we also had infected board files, so I had to do a complete reinstall and recache, then weed out what I needed to in the database.
If it's something you feel you should PM me with, that's fine...but I mean, every person with a browser has access to a source code. No big deal, though.
Maybe I can help with a solution.
