Viewing past stage + mouseover

[toolman]

Hi

I am having trouble viewing all of my stage. I have images going off to the right, but it will only let me see up to the edge of the stage(white). How can i view past this?

also

I have this bit of coding for a flash movie where the user clicks on a button to make something move. However i want it so it moves when the mouse goes over it. How can i change it:

on (release) {
 loadMovie("clip7.swf", "_root.screen");
}
