It may be a setting on your computer, not necessarily the mouse.
I don't think so. I didn't change anything except my mouse.
and there
is a lag time between when my mouse moves and the computer responds.
I also had a low rise mouse before and I find this shape bothers my hand.
I may just get another one and save this as an emergency backup. (My old one had begun bouncing the screen up and down during scrolling.)
