In addition to the ortho function no longer being available in selection commands like CP (crossing poly) or fence, I have discovered 2 more issues:
1. Match Properties cannot be carried between multiple drawing files. In previous releases I would be able to match properties from an entity in one drawing and then toggle between all open drawings and apply that property to entities in each drawing. I can no longer do this reliably.
2. As I toggle between open drawing files using CTRL-TAB and perform a command, say MOVE, I cannot move onto the next drawing unless I move my mouse after the completing the MOVE command.
I just wanted to confirm Dean's post and stress the importance of reporting any issues you find to the link he shared. All submissions are reviewed so it is much appreciated when customers report the things they are seeing.
Thank you
