Chatroom format problem

I posted this a few days ago.........

"When I log on to a chatroom a new Internet Explorer window opens with a text area/input box thing in it in which I should be able to read other users words and write my own.
But the problem is that the box is only a couple of centimetres wide and high so it's very difficult to use!
Can anyone tell me why it is doing this and how I can fix it?

Your help greatly appreciated
Caras"

I have looked at the How to' stuff on the chatroom site and it says I need the Java RTE.
I followed the link to get it but could only find anything for OS X. Can I get it for 9.1? And, if so, where?

Thanks
