So I vented to my VAR recently about how 2016 is the most unstable version I've ever used. It crashes pretty much on a daily basis. Besides dealing with the "read-only" issue, which forces me to restart SW, I've had SW crash by just starting a new drawing, inserting a top view, and then trying to move that view. I've had models that needed to be saved only to see that the asterisk after the file name won't go away after I try to save. If I try to close the file it says that changes were made and asks if I want to save them. I say sure! Asterisk does not go away. If I say no, all my changes are lost!
