Hi, I hope this is the right section. I was wondering if there was a way to enable scroll button click scrolling in Safari 4 on Snow Leopard? I'm sure there's a proper term for it, but what I mean is when you press down on the scroll wheel and a circle appears on screen with two arrows, when you move your mouse up or down it allows you to scroll through long documents quicker. I think Firefox and Internet Explorer have it. I read that USB Overdrive might be of use, but it wont recognise my mouse (Logitech MX 620). Any help is greatly appreciated, and thanks in advanced.
