Just got my new MacBook Pro 2.8 this weekend. I am having an issue with the trackpad. I cannot get the two finger scroll to work. My MacBook this is brialliant and works like a charm. At first I thought it was a config issue but it seems to be on by default on the control panel. The 4 finger expose works, the single finger works fine, even the three finger swipes work. But using two fingers to scrool a web page or word doc does nothing. Any thoughts?
