Apple trackpad

[.Shaun,,]

I recently bought a trackpad for my imac, I have set up it up and can only use it for moving the cursor. I can't use it to scroll, zoom in and out etc etc. When I go in to system preferences I only get mouse and keyboard, trackpad should have its own program. Any ideas on what am doing wrong here?

I also had the wireless mouse and can perfectly scroll and things on that so, I know am not doing anything wrong with how am using it. :P

I doubt this is it but if you're running an old version of OS X, you might need to download support manually: http://support.apple.com/kb/DL1066?viewlocale=en_US

Otherwise do you have a third party software which could be interfering with the trackpad? Maybe a third party application for your magic mouse?
