Discrete Scroll
Fix for OS X's scroll wheel problem
Installation
You may download the binary here. It runs in the background and allows you to scroll 6 lines with each tick of the wheel.
It needs to be run each time you boot. If you want this to be automatic you
may go to System Preferences > Users & Groups > Login Items and add
DiscreteScroll to the list. If you want to undo the effect you may launch
Activity Monitor, search for DiscreteScroll and force it to quit.
