This is my first post so hello to everyone! I’ve recently been intrigued by flash sites which resize automatically to fit a browser window and have a scroll bar fixed to the right side. This is what I am talking about:

Does anyone know of tutorials explaining how to accomplish this? Or can explain it to me?

Thanks A Billion
