More concrete information. Previously, only the idiotic Thinkpad driver required that there actually be real PM scrollbars on the window in order for scrolling work.
This driver so nicely extended that to all PM windows. So my Thinkpad fix has to go in for all scrolling mice. Second, it appears that not have "Use PM scroll" checked doesn't work at all. I believe that what this is supposed to do is emulate scrolling my using the up and down arrows on the keyboard. I haven't found a single app the scrolls if I uncheck Use PM scroll. What fun. I'm going to contact the driver developer about this. This is a joke.
