Question

How can I stop Emacs (Cocoa OSX, version 24.0.91 from http://emacsformacosx.com/builds) making noise when scrolling and hitting the top of bottom of a buffer when using the touchpad of my Macbook? I know I maybe should use the keyboard to scroll, but I'm so used to using the touchpad of my Macbook.
