BERI~  Same problem for me... it installs, I restart, then open up preferences and put in all the settings I want, only to have it not work =(

iBook G4 with OS 10.3.9

I really want the 2 fingered scroll and now I'm stuck with iScroll which keeps resetting my prefs every time I shut down computer =(

Message to the developer: please fix the problem! Most of us can't use the app at all when it's like this. Same for anyone else who knows how to fix the program.

CRUCIAL  Just tried this on 10.5.

The preference pane says it is loading, but nothing happens. Thankfully the uninstall script works.

REDFURY  Works GREAT on my 15" G4 Titanium Powerbook 1Ghz.

Calibrated and set options easily, and in less than 5 minutes I had a "scrolling" trackpad.

I dunno if it helps, but here's some info directly from the Apple Website

"The driver is entirely based upon the original Darwin ADB trackpad driver with the information for how to activate `absoluteÕ mode taken from the ScrollPad project. The preferences daemon and the two-finger scrolling code is taken from the iScroll2 project.

JUKI  Just can't get the scrolling feature to work;

programmed it per instructions but it's totally unresponsive.

Didn't test any of the other features since I'm only interested in scrolling.
