In the very near future a chat update will be released, this update will mean chat will no longer support Interner Explorer 5.5.
If you're not sure which version of IE you're running, you can find out easily by selecting About Internet Explorer from the Help menu. If it says version 5.00.xx, then you're running IE 5 or later.
You can download a more recent version from www.microsoft.com if you require any help with this please do not hesitate to seek the help of a navigator.
