Usually you can go to the 'Help' menu and there will be an option like,
"About Internet Explorer" or "About Communicator..."
When you click on this, it will give you all kinds of nerdy details about the browser version etc etc.
This is probably all a bit academic if you're on a Citrix system, because it's unlikely that you can get a change of browser. It might be worth doing anyway.
On a nerdy note, it really annoys me a bit that MA doesn't work properly with the Opera browser, and only looks really swish with IE. 'Tis a shame.
