10.7 Macbook Pro 4,1 Right Click Fix

In the release version of Mac OS X 10.7, there is a bug that prevents secondary click working with two-finger click on the Macbook Pro 4,1. The only way to right-click is using Control+click. To enable right-click using two-finger click, run the following in Terminal:

defaults -currentHost write -g com.apple.trackpad.enableSecondaryClick -bool YES

After doing this log-out and log-in again.
