Hi

Suddenly in all my Microsoft office programs the vertical scroll bar no longer moves the pages up and down when i click on the space above and below the scrolly bar. Instead the scrolly bar moves but the pages stays where it is. The horiztonal bar works fine. How do i fix it?

Thanks

Tried uninstalling and reinstalling and creating a second account but still no luck. Only affecting Word. If i go to System Preference > Appearance >Click to scroll bar to: and click jump to spot that clicked, it works. But Word still wont work when i have 'jump to spot that clicked'. Any help
