Marble Trackman Scroll with holding Button only on Windows

I bought a Logitech Marble Trackman. I am used to hold one button and roll the ball to scroll under linux. Now I am working under Win8 and installed Logitech SetPoint. Now I have Universal Scroll and AutoScroll as options and both lock the scroll function. I need a second click to deactivate scrolling.

Is there a way to scroll only with button 4 hold?

How do I scroll with my Trackman mouse?

The scroll ring encircles the trackball, allowing you to rotate it using your thumb and fourth finger while your hand is still over and in contact with the trackball. This allows you to move your cursor and scroll up and down at the same time!

I found a solution after a long search. It's this simple:

throw away LogiTech SetPoint
Install e.g. X-Mouse Button Control from http://www.highrez.co.uk/downloads/XMouseButtonControl.htm
Configure everything you want.

Poor Logitech.
