Active Screen Property does not update

[Connor551]

Can anyone validate this?  

I'm having some screen sizing issues, so I threw up 4 labels on my app:

Parent.Height
App.Height

App.ActiveScreen.Height

'Screen name'.Height

App.ActiveScreen does NOT update with changing/resizing of the screen.  Is this intentional?  I thought this was supposed to reference the current screen's properties like height and width.  All of the other indicators moved/responded to changes in screen height.
