irc help, Leonard Cohen chat

[heyjudah]

Sorry to bother you:

http://www.leonardcohenfiles.com/frame.html
Chatroom - always open
javascript:avaa_chatlogin('http://www.leonardcohenfiles.com/chat/')
works fine on desktop (XP) (wired)
but doesn't work at all on laptop (vista) (wireless)
I have reinstalled java.

http://webchat.blosers.org/cgi-bin/irc.cgi
runs extremely slow on my laptop (vista) (wireless)

Do I need to change some security settings on vista laptop?

Thanks!
