I see that we can adjust pointer speed but is there any way to adjust scroll speed? Any time I need to scroll it's very erratic and blazing fast, which makes it hard to read hard to control. Any suggestions? I had so much enthusiasm when I got this device but it's turned to frustration. This device is not ready for primetime. And I have only experienced it with the latest update, I can't imagine how frustrating this thing must have been with the original software.
