Hello,

I've got 13.04 on a Macbook pro 8,1

I'm having issues with two fingered scrolling,

I can't select multiple items from a long list,
because when i touch my fingers on the pad to scroll it selects as if I was doing a 1 one fingered tap.

and regularly,

having two fingers on the pad trigger rapid cycling through all the apps in app switcher.


Here are my touch pad settings from synclient -l

Code:
