Hi all.
I was working and a message displaying fatal error appeared on my screen.
after saving the work, I reopened the file and unfortunately I can no longer delete with the "Delete" or delete key from my keyboard.
Also after when I select a line and I right-click the delete, move and other options no longer display.
I restarted the post and I even reinstalled AutoCAD 2016 but still the same problem.
Really I don't know what to do anymore
