Two-finger scroll not working on MacBook Pro
Any idea why I am unable to scroll up and down in Safari and in other applications using the laptop's trackpad? I have to move the pointer on top of a scroll bar, click and hold with one finger, then scroll with another finger. Looking to scroll pages without dragging the scroll bar.
I have already checked the Trackpad settings in System Preferences.
Thanks.
MacBook Pro (Retina, Mid 2012), OS X Mountain Lion (10.8.2)
