I'm using a macbook running Leopard. A few days ago my roommate dropped my macbook onto the fl9oor from about 3 feet in the air. Now, the middle row of keys, as well as the numbers keys at the top type like this: a1s2d3f4g5h6j7k8l90 (with shift) A!S@D#F$G%H^J&K*L() This problem did not occur immediatly after the macbook was dropped. Rather 20 or so minutes after using it normally. Last night the problem seemed to magica1lly go away. But then today I was typing and mid-sentence it started having the same problem. Obviously this is a pain because I have to go back through and delete all the numbers, so any help would be greatly appreciated!
