It also has more parts
The other parts you have to make seperately. Your start menu parts are...top part, bottom bar, programs list(left), more programs background, and places list(right).
The other parts are used for the start menu (like the item mouseover) but arent really part of the start menu (am I making sense?). Get your start menu pieces in there correctly first and the rest you can worry about once your done with that.
If you get stuck or have any more questions, just ask!
