[Can't see certain people in Local Chat]

This is still happening to me (the boss she mentioned lol). I log in and enter a room and things are fine, i can see everyone typing and they can see me. Then after a while, its as though gradually, one by one, people cant see what im typing. I can see it, but no-one else can, and i can see what everyone else is typing too. IM works fine though. Every time i restart firestorm, it fixes things for a little while and then it starts happening again, usually after about 30 minutes. I'm trying to run a club, this is NOT helping.
