I currently use two 2011 iMac's equipped with Mighty Mouse - the round mouse with a rubber scroll ball. When I go to scroll through pages or folders though, it is inverted. By this I mean that down is up, and up is down. I have been told there is a "natural scrolling" option somewhere in the settings, but I have yet to find it, only mentions of using it with the trackpad. How can I disable the inverted scrolling using a Mighty Mouse?
I am running OS X Lion. The mouse is wired
