Im running Windows 7 64 bit via Parallels. I'm using the magic track pad. On the Mac side, scrolling is smooth. On the Windows side scrolling is clickety (by line) as if I had a mouse with a scroll wheel that clicks. I've gone into the control panel under mouse properties and dialed the by line scrolling to one line but it's still clickety. How can I get the smooth scrolling that I have on the Mac side over on the Windows side?
