A co-worker tells me when he opens a drawing then minimizes it and then opens a new drawing to fiddle around with, when he closes it and doesn't save and returns to the first drawing, when he runs commands he gets "No Null Object" errors. He can click OK or whatever on the error messages and continue, but they constantly fly in his face. Is there a way to fix this?
He's running AutoCAD 2011 Maps 3D x32 on Windows 7 x64.
This could be something on his software support search path, it is hard to tell like this.
I will recommend to open a ticket for this so we can troubleshoot with him.
