I came home from work tonight and she told me that my 1 year old son was pounding on the keyboard earlier. well, when I am looking at the screen, the right hand side is cut off and the dock is gone. When I move my mouse to the right, the entire desktop scrolls to the end of the finder bar. When I move my mouse down, the desktop scrolls and the dock appears. how do I correct this? or is there a system restore on a mac like windoze has? Thanks for the help. This is freaking me out.
