TwoFingerScroll
Official 1.0.6 http://code.google.com/p/two-finger-scroll/
Unofficial 1.0.9 http://forum.tabletpcreview.com/hp-touchsmart-tm2-wacom/38405-t
Disable Synaptics's own two finger gestures and use this program instead.
You will find your two-finger scroll much better, and two-finger tap as
right click is very handy. I never miss Mac's touchpad any more.
I am using 1.0.9 because it supports reverse scrolling, and two finger tap.
Somehow it's three finger gestures are not quite well, but I don't care
about it any way.
