Thanks for the post. I actually found out somewhere after the fact that when you install OpenGL 1.2.1 (or perhaps update any previous version of OpenGL??), which I did when I downloaded the Cro-Mag Rally Demo, that you have to reinstall the ATI video SW update 1.0. When I did this, my fast scrolling speed resumed. It did slow down again for some reason and I reistalled the update AGAIN and so far so good.
