Stuck at first screen and feeling pretty stupid!

I have played alot of hidden object games, none of the "Fear For Sale" though, and can usually figure out how to use the special features. Not the case here with the zoom. When you click on the round box it says to find the contents, which are flowers and a butterfly, but that you can only see them in some zoom mode. How do you get zoom to work?

When you see that message, you're already zoomed in. The fragments are scattered around the perimeter of the object you are completing.
