[flexcoders] Explination Wanted - History Management code

[dorkie dork from dorktown]

I have read the documentation on the HistoryManager and it seems overkill. What I want is very simple. When I click a button to go to the next screen I want to save the current state. Then if I hit the back button I will go back to the previous screen. 
<mx:Button label="Change to State Two" click="{currentState='secondState';HistoryManager.save()}"/>It seems that I have to set my Application to implement mx.managers.IHistoryManagerClient
, register the Application with the HistoryManager class and then create save and load functions. It may be my code as well but it seemed to break my tab navigator history management or disable it. Not sure. Anyone gone before me know what is going on or an easier way?
