If you’ve been using computers for as long as I have the new style of scrolling in OS X 10.7 (Lion) is far from, in Apple’s words, “natural”. This is easy to change back to the previously used system which was in fact, natural.
In order to do this simply open up System Preferences (in the Apple menu), and then navigate to the “Trackpad” section. Within here go to the “Scroll and Zoom” tab and then unstick the “Scroll Direction…” checkbox. Once you have done this your scrolling should be back to normal.
