I tried searching the forum for this, but found nothing. I apologize if it is a repost. I'm running RC2, with XP/SP2 as guest. The trackpad works wonderfully for moving the mouse, left-clicking, two-finger right-click, and two-finger vertical scroll. However, horizontal scrolling is not working. I know this is a release candidate, and that you probably don't focus on adding new features. Still, I hope you can add this feature in, I guess, Parallels Tools. Thank you very much for a truly amazing piece of software!
