I've been having a few odd problems with typing on the MacBook in the last few months, and wondering whether anybody had any ideas, or similar experiences. It's a Unibody alu, and the problems have existed as long as it has. I don't think they're keyboard issues, but something happening in its demented brain: a) MS Word: I've noticed that if I select a piece of text to type over, when I type the new word it's often missing the first letter. For example, if I want to change "Dog" to "Cat", I highlight "Dog" and type "Cat", but what actually appears on the screen is "at", minus the C. b) Safari: Another problem with highlighting, which I'm noticing in Safari, e.g. when typing up a blog post. If I select some text to replace and then start typing, it not only replaces the text selected, but the same number of letters again. For example, if I have "Dog Joe Egg" and I select "Dog" and type "Cat", Safari deletes "Dog", then jumps ahead and deletes "Joe", so I end up with just "Cat Egg". Intermittent, most noticeable on Wordpress. c) Copying text: I'm noticing this primarily in Word again, but I think it happens elsewhere too. Sometimes (usually, even) it just doesn't pick up when I've hit Apple-C to copy, and I keep finding myself pasting old clipboard material, rather than the last thing I tried to pick up. This is exactly as annoying as you can imagine it to be, and probably happens more often than not. Well, there you go. Any ideas?
