Hi Bennett. The steps creating the issue are kind of random to me. I will be using the trim tool on say a half a dozen lines and then all of a sudden the drawing freezes. When trying to save/close, I receive an ACAD message noting the drawing should be recovered. When I have recovered the drawing after this event, it shows anywhere from 0 errors to 177 errors. This issue was happening at the same time I was having MText crashes which have been fixed, but alas this issue still prevails! I was unable to reproduce the issue on a blank drawing. Could it have something to do with the MText issue I was having on this drawing and not the blank drawing?
