I am confused by the 'animator man' sample - could someone please point out where I am going wrong?

When I drill down to look at the elements, I find A background and a button. I deselect the background and open the button. The button then has elements for 4 states, so I open 'normal'. This opens a layer window which does not show the whole picture as I expected but just the lower right quarter. Why is this, and is there a way to bring back the whole picture to edit it?

sorry if I sound ignorant - I am ;-), I'm just very new to all this and the help doesn't seem to explain.

thx in advance

Paul

PS are there any decent tutorials around for using 3D Flash Animator?
