I just got back from a Mac store at my mall (and boy was it CROWDED). It was my first time messing with a mac and I loved it. I loved everything about it but one tiny thing. Whenever I would open an application, it would never open all the way to where it would take up the whole screen. And I would click on the expand button but all it would do is get slightly bigger. When I get my iBook will there be a way for me to set the default window size to where it takes up the whole screen when i open an app?
