I've just bought a Logitech VX revolution mouse and got it all set up fine, apart form the scrolling. If I have the ratchet mode enabled, it scrolls very slowly, even if I have the scroll speed set to the fastest setting . I can get faster scrolling by using the free wheel mode, but this doesn't seem to give much of an improvement in World of Warcraft . Has anyone else managed to solve this? Annoyingly, it works much better on my PC (although there are other issues with that ). Thanks, Dave.
