The video after the jump is wonderfully helpful. If you are having a hard time understanding computers, you may want to watch this. Just imagine that the mouse is like the controls for a claw game. It controls the pointer on the screen because, just like as in the claw game, you cannot touch the pointer because it’s behind the glass. Also, make sure that when you press down on the mouse button, you release it like it’s a hot potato. All good tips, btw.
