two-finger scrolling doesn't work
I upgraded my recently purchased MakBook Pro (13") to Lion today and then I migrated my complete data (incuding user preferences) from a copy of my iMac which used to run the latest version of Leopard (not Snow Leopard -- this is a 20" iMac purchased about 3 years ago). After the migration the two-finger scrolling (which I quite enjoyed before the migration) stopped working.
I have checked that System Preferences > General and System Preference > TrackPad options are all checked to have the scrolling work. All the other gestures work except the two-finger scrolling. Scrolling works in other (non-migrated) accounts on the MacBook Pro.
Any ideas why this is happening and what is the remedy?
MacBook Pro, Mac OS X (10.7)
