I have the Suface Book and have noticed the mouse jumps around while I am moving it with my finger.
I have found the if you slide your finger to move the cursor and inadvertently tap(and release) with a different finger, the curser will move back to the start of the mouse drag.
How do I turn this feature off. It causes the mouse to move around. I originally thought it has something to do with the touch tap option, but narrowed down the cause.
Slide your finger across the mouse pad, and while it is moving tap with the other hand. The mouse will warp to a new location. In order to get this to happened you must tap and not hold.
I use my middle finger to move the mouse and my index finger on the same hand to click. This allows me to drag a windows, but I don't think about it when I do it.
Please help. I just got the Suface Book but this feature is driving me to consider returning.
