I've noticed that Microsoft Optical Mouse with four direction scroll wheels doesn't work in horizontal scroll mode. I installed the drivers both in Tiger and Parallels/XP and it works fine in Tiger but not in XP. I guess the horizontal scroll input isn't getting passed to the Parallels/XP? Any plan on making this work? I've also noticed that somewhere in this forum others have brought up the same issue with Mighty Mouse. BTW, RC2 works great! I just paid for a copy. Keep up the good work.
