Thanks for reporting this - it looks like that's a bug when the 3D view is set to be parallel rather than perspective.

That's probably a lingering bug where some things had assumed that a parallel view was always an ortho-plan one, since in MoI v1 that was the case.

It should be easy to tune up, I'll take a look.
