WindowHeight in LetterBox Scale issue

Hi, everyone.

Sorry if this has been asked before but I couldn't find a proper solution.

In my demo, I check WindowHeight so an object will bounce when it gets to the bottom of the screen.

The example works great when not maximized in NW.js window.

If I maximize the NW.js before the sprite gets to bottom it will not bounce like if the Width/Height coordinates have changed.

Is this a default behaviour in the letterbox scale mode?

Here's the CAPX file:

Is there a way that I can make this work no matter if the window is maximized or not?

Thank you.

EDIT:

Sorry, guys.

I think it's the "ViewportBottom" expression that I was looking for and not the "WindowHeight".

I come from other non-HTML5 programming languages and I have missed something like:
