Micheus ... Selection Groups scroll vs Geometry Graph Scroll

[ggaliens]

There is something very hard to deal with with regards to how selection groups become "invalid" and then deleted. It probably comes from using the wings_sel:valid test to see of a group should be removed. I think the proper or ideal test would be more nuanced than just that ... more tricky.

I hide and re-show objects all the time. And if I SAVE a file with hidden objects ... pretty sure selection gorups are deleted. Not a horrible behavior ... but perhaps not the best behavior either. IT has caught me off guard many times ... selection groups disappearing when I don't expect it to happen. It should happen just on a geometry change to #we{}.
