technical LJ question

Does LJ create persistant active content upon leaving the site?

I'm getting active content warnings whenever I go to my (local) homepage after visiting LJ, and I know there's no active content on my homepage.

Battlestar Galactica!

BG's new season starts tomorrow evening!

This will be their final season, but they'll be launching a new related series this fall. (Hopefully not called "Battlestar Galactica 2008")
