Now, if you switch back to Main.fla and click off the stage you will see the Properties for the page in the Properties Panel.  There you will see a field that is new to Flash CS3 called the Document Class field.  Here is where we put the fully qualified path of our DocumentClass Class. (see Figure 3-1).


Figure 3-1: Put our fully qualified path of com.identityMine.documentClass.DocumentClass in this field. 

Now if you run your application you should see "DocumentClass Initialized" in our Output Window. (see Figure 3-2).


Figure 3-2: Our Output Window shows our trace statement so we now know that we have succesfully connected our DocumentClass with our Main.fla.

Next let's go on and create a very simple navigation button and create a Class for it.
