not sure if anyone has a similar issue, but i recently purchased a new MBP friday and i have already noticed issues with the cap lock and the enter keys. sometimes when i press enter or the cap lock, it doesn't register. now this doesn't happen all the time, but enough to notice it being a problem and i noticed that i have to press dead center of the key to get it to work sometimes. when i hit return on the left side of the key, it will indent down like it's suppose to but no action is registered. i read similar topics about mac keyboards having this "function" but i don't believe it's anything intentionally designed. does anyone recognize this problem? my macbook pro is only about four days old, so i'm planning on visiting the apple store where i bought it to get it exchanged.
