Two questions: change the width and other with IE.

[Krom]

Hello everyone, I'm new here and I have two questions:
I wonder if you can change the width of the chat, and high and I saw that if I did but I wanted to change the width to make it smaller.
The other is curious, fuciona perfect with IE but if I put it in an iframe does not work says I have cookies deshabilitadas.Con Firefox or Chrome is going well.
Sorry for my English and thanks. Greetings.
