hi! i just transfered my old user account from my previous macbook pro to my new macbook pro april 2010 15" i7. the momentum scroll effect on the space bar (in for example safari) is not working. it's there when i'm using a different account on the same new macbook pro. regular momentum scrolling on the trackpad works just fine. i suppose it's because of the transfer from the old account. does anyone know how i can re-enable this feature? maybe through terminal? thanks in advance!
