I don't know if you also have problems like mine, but whenever I log on to my YM, I keep on being disconnected and reconnected behind office firewall. Our PC users do not have problems like these with their YM's. I have another colleague, mac user, also experiencing the same problem. I know, I know we shouldn't even be chatting at work. Hehehe. But we use it communicate with each other at work. I don't normally log on anyway. Just sometimes.
