I just got a new Chromebook (my 4th), and when I use any double finger function with my fingers together, it doesn't work. Most significant is the scrolling function. If I have my two fingers together and try to scroll, the arrow just goes up and down as if I am touching with one finger, but if I spread my fingers apart, it functions normally. It only does this intermittently--at times it works properly with my fingers together. The longer I am on it, the worse it gets. I have already returned and purchased a replacement, and it does the exact same thing. Since it is only intermittent, on both of the machines I purchased, and works properly when I spread my fingers apart, I do not think it is due to user error, defective machine, or slow loading time. Chromebook is fully updated. I really want to make this device work, but I don't know that I can live with this issue. Anyone else have this machine and experience the same issue? Any way to fix it??
