macbook keyboard keeps highlighting and overwriting text. HELP
I have a 2008 black 13 inch macbook, that had a keyboard replaced 13 months ago as half of it stopped working!
Now it keeps highlighting and overwriting text of its own accord, jumping to random parts of a page. I don't know how to stop it, but as i need to type around 5000 words a week for work purposes I really need this sorted ASAP! I can't currently afford a new laptop.
MacBook, Mac OS X (10.5.8)
