Keyboard for Mobile App Prototypes messes up layout


Prototyping a mobile app with a StatusBar and NavBar. When focus on Search field the keyboard presents and slides the entire prototype up so that the top portion is out of view port.

And related to this the TabBar also slides up.

Obviously none of this is how mobile apps really work.

So doesn’t anyone have any reasonable workaround for getting Axure to support realistic mobile app behaviour? Or do I have the manually recalculate DO sizes and scroll location each and every time a field gets and looses focus?
