Some of you probably already know about this, but for those of you that don't... MacAlly has released OSX drivers for their USB mice and trackball products. You can find them here and download them for free. I have installed them on my TiBook since I have an iOptiNet mouse attached. You now can set the scrolling wheel speed, and the function of clicking it (set mine to double click to make things easier). You can also set the cursor speed within the software, or leave it as set by the OS. For anyone with a MacAlly product (mouse or trackball), I suggest downloading these latest drivers for OS X and giving them a twirl.
