With upgrading to the new version of Os x i.e. Lion os x, the scrolling pattern has changed and is reversed. Kind of uncomfortable if you are used to using the older and more accepted version of scrolling pattern.

Following is how you can revert OS X Lion’s page scrolling to the old direction.

1. Start System Preferences

2. Click Trackpad.

3. Uncheck the box that says “When using gestures to scroll or navigate, move content in the direction of finger movement

4. This should get the old scrolling behaviour back.

The change only affects the current logged in user.
