> does anybody get the issue using a mouse and not a touchpad?
Yes, my workstation has that problem to. Jaunty, upgraded from Intrepid.
Sensitivity slider has no effect.
The default sensitivity with a mouse is acceptable so it isn't a huge problem.
A also have a Asus Eee and the problem is present there to, and with a touchpad the problem is annoying like hell. (Sensitivity is at acceptable levels if I connect a mouse).
