Mouse pointer speed

[Bent Bracke]

Hi

Sorry about the lack of details.

It is possible that it's just too fast. I'm simply having difficulties clicking on anything because the mouse pointer moves around so quickly. 

I'm running genode with qemu on Ubuntu on macbookpro via parallels. 

It is a usb trackball which works fine on Ubuntu and OS X.

Kind regards
Bent Bracke
