Hi, I have a very strange problem with a drawing - I'm unable to copy/paste any object. When I click to copy, a message appears "_copyclip 1 found", but when I click to paste, a message says "_pasteclip" but nothing happens. I found some similar issues on this forum but nothing helped to solve my problem. Ultimately I deleted all the objects on the drawing, inserted a text, but the problem is still there. Also, I can't drag any objects.
I'm attaching the drawing so you can see it. The same drawing produces the same issue on another PC with ACAD.
