Sorry dude, it has been discussed quite a bit, but the bottom line is, you are stuck with mouse movement. I'm on a lappy too, so I hear you.
As for your first question, I'm not sure what you mean by 'locked'. On a mac you can always Command-Tab from the Avadon window to another application. I'm pretty sure you can also move your mouse outside the window and click. (the mouse becomes invisible so you have to guess, but it's not hard).
Now, if the game kept running while you were checking your email, THAT would be amazing. (walking = boring) But I know that's asking too much.
