ThomThom, that's an interesting point. A couple of weeks ago or maybe it was last week, I have CRS, someone sent me a model in which something they were trying to do wouldn't work. I think it was plugin related. I copied the geometry to a new SKP session and it worked just fine.

That didn't work for me. I tried it on several machines. If I kept right-clicking on selected geometry it's slowly start disabling menu items. Very odd.
