That usually happens when you don't trust the Applet's signature. When it asks you if you want to Run or Accept the Applet make sure you hit Trust/Run.
if that still doesn't work, is it possible your running Vista on the computers with the problem? :P
I'm currently using a Vista and I'm not experiencing any problems and I go on the IRC chat quite often, I do accept the java signature.
