When typing on the keyboard of my Dell laptop, my palm occasionally slips over the trackpad, moving the cursor to another position in the text or putting focus on another window.
I'd like to find a way to automatically disable the trackpad when a mouse plugged in.
I tried that : http://superuser.com/questions/20101/disable-trackpad-when-mouse-is-plugged-in-windows-7-macbook-pro but it doesn't work with my computer.
