The position in GeoData -> Create Houses, in which it is supposed to enter latitude and longitude of house, has no effect.
Is it right behaviour and is it a design feature?
Or wall may be marked to recompute and press F5 (to refresh), to get the window.
I found that right-clicking on window is not solving the issue. I had to right-click "wall" in tree to mark it for recompute, and then hit F5 worked for me.
