I'm not sure if this is a mod problem, a FireFox problem, a Flash problem, or a FlashChat problem.

I just installed FlashChat with this mod and it works great in IE7. With FireFox, a blue box covers up the chat interface when you scroll down (see screenshot). When you go strait to the chat directory (bypassing the mod) it's fine.
Any ideas?
Thanks for the cool mod. Great work as usual, Paul!
