I've been having some problems with my Macbook Pro (2.33GHz, 2GB RAM, about 1.5-2 years old) keyboard. If I start typing in a field on a website or on iChat, the text cursor will sometimes randomly insert itself several words or sometimes letters away from where I was originally typing (I'm having this problem as I write this thread, and it's extremely annoying). Sometimes I'll be typing and the whole field will become highlighted randomly without hitting command a or using the mouse. And yet other times random other windows will become active. For example, I'll be typing a line to a friend on iChat, but in mid-sentence a chat window with another friend will become active without me selecting it and my type will go to that window. Any suggestions to get it fixed (software update I'm hoping)?
