BoxEdit command very slow on many objects

BoxEdit can be vary useful, but it gets really slow when more than a few hundreds of polysurfaces are selected. I think that it would be great if it could be improved.

It may also completely freeze Rhino trying to process larger selections (not transofrming them, just selecting).

Are you running the latest SR?
It used to be the case but for a few months now it’s been fixed and should work OK on many objects…

Perfect, thanks
