This error occured using a public chat room. I requested a private chat with another user, typed in a message to that user. The private chat apeared on other user's window fine but Firefox spit out this error (no error appears for IE 7). Fire fox gives the option to continue the chat fine, and the chat works fine but :
Error #2044: Unhandled IOErrorEvent:. text=Error #2032: Stream Error.
