The trackpad on my new MBP 17" has, essentially, no function. I can move the cursor around, and can scroll via the direction arrows, but cannot select/click with the trackpad. Enter/return functions, but half the time I've no idea or control over what it is I'm selecting. I have, of course, been entirely unable to use Parallels. I have the latest build of Parallels 6, btw. Would love a suggestion or two, thanks!
