Xref makes original read-only

Hello, previsouly I didn't have this issue, but lately when I attach an Xref to a drawing, and someone else on the network want's to open the original, it says that it is in use and can only be viewed read-only. Then I have to close my drawing, and after that person has opened the original file I can go back to working in my drawing that contains the Xref. Could someone please tell me what could cause this?

Maybe this?

Yesss!! That did the trick, guess I ad changed the option in some mysterious way . Now i know what it stands for, thanks a million!

me too, i've never care to know about that before

I think I red it in some smart-a$$ book that it should be changed to that setting (which caused the problem), and it didn't explain why nor what it does, so I guess that was when I changed that setting

thanks for asking this question.....it worked for me too
