On the right hand side of the Dock there is a Download Stack (not sure i have the terms right). Just to the left of that there was another Stack?, Document? that I accidentally dragged off the Dock. The thing is that it then disappeared. It's not in trash and it's not on the desktop. Can anyone point me to the name of the missing item and how to get it back? I am a new Mac user so not sure of all the names of things and what is important...yet. This is all for Mac OS X Lion. Thanks!
