Cubase pro 9 multiple mouse issues in windows 8.1

Since I installed cubase 9 my mouse doesn’t work fine, double-click is very often inactive I have to click sometimes 3 or 4 times to run an action !!!
I crashed preferences but it’s the same, Even playback or recording is not running and when I want to close cubase too I have to do : ctrl-Q to close instead of click 3 times !!!
It’s a Nightmare I think I will re-install cubase 8.5.

I don’t really have this problem, but it is because the mouse is moving while clicking. It has to be stationary.
I use a lot of mouse acceleration, with a slow default mouse pointer movement. That makes the pointer move extremely slow and precise with subtle movements and at normal speed with faster movement speed of the mouse.
I know that is probably not what you want to hear, but it works really well when it’s dialed in.
