Title: Good trackball but not for carpal tunnel
Review: The trackball needed to be lubricated and then it worked great. This trackball did not help my carpal tunnel syndrome as I hoped. I found a problem with Logitech's driver for OS X 10.4.8 in my Core Duo Mac. The trackball's scroll up button didn't work when I reached the bottom of an HTML message in Apple Mail, similar to the up arrow on theApple USB Keyboard - Whitewhich has never worked there in Mail either. With the 10.4.9 update, the keyboard's up arrow still won't work there, but the mouse will scroll up. I used anApple Mighty Mousefor a year before buying this trackball. It scrolled up OK in Mail but it didn't help my carpal tunnel either. Instead of this trackball, I just stopped using a Logitech Marble Mouse with my left hand. It's given me the same symptoms so I'm back with limited right hand use of a Mighty Mouse, trying to use more of Mac OS X keyboard shortcuts and the Universal Access mouse keys feature.
Is the review positive or negative?
