Double clicking object groups selects all objects

Hello.
I have a little bug to report. It appears that double clicking the Object Groups in Scene Explorer selects all objects in the scene.

It is intentional. Why do you think it is a bug?

Well, in all implementations of hierarchy trees in operating systems or other software that I had contact with, double-clicking the parent node reveals its children instead of selecting them all. In NVil it does both.

Fixed.

Thank you very much IStonia!
