Guess . . . , just to let you know. Since the update to High Sierra 10.13.5 the kensington expert mouse works perfectly.

Hello RGyori, Thank you for your response. I've indeed upgraded the Kensington mouse driver, but that update was from April 2017 and the upgrade to macOS Sierra has happened in May, and soon HighSierra is coming. I have contact with the store where I bought the mouse. The 2-year warranty is over. But the warranty on Kensington's website is 5 years. I also told the relevant store that the Kensington mouse does not work with the latest Windows 10 Creators update, and soon Windows 10 Fall Creators Update is coming. The relevant store will contact Kensington for a driver upgrade 'again', and will keep me informed.

I'm glad to find this thread, I am not the only one with this problem. I did contact Kensington Support twice via email but they haven't answer yet. Here is the Kensington Expert Mouse use on a macOS Sierra. Since 19 May 2017 (after update to macOS 10.12.5), suddenly the mouse doesn't work perfect, the scroll drive is still scrolling, but does result on the screen, it does not scroll anymore.
