1. I notice a slight increase in noise coming from the harddrive when i scroll through the dock, is this normal? 2. How the heck do i use expose on my 15" pb? I know you are supposed to press F9 but it wont work because it is a function key that is used for something else. 3. The text on this screen seems to be a little soft (ie fuzzy), is there any way to remedy this?
