I'm having an issue with Trim and Extend. Specifically with the shortcut method of hitting "Enter" instead if selecting objects. It's trimming back to beyond the closest object and/or extending beyond the closest object, but not in a way that's predictable. It doesn't seem to matter what the nearest object is (block entity, pline, etc.) And, yes, they are all on the same plane or whatever. All flat as pancakes, and the regular Trim/Select, etc is working OK.
I think I have something for the wishlist....don't muck up the stuff that works!
