User worked on pipe drawing, opening through Document Manager, saved and closed.
The next time she went to open the drawing through Document Manager AutoCAD hung up with 0% progress.
Note: Opening drawing by right-click in Document Manager and select Edit...
Verified that no one else had the drawing open, checked network location for lock (.dwl) files from this drawing - none exist.
Tried to open drawing from Document Manager with right-click - Edit with Native AutoCAD: Notified that drawing was already open or read-only, open read-only? Select Yes, drawing opens.
Verified that the drawing is not marked read-only, there are no lock (.dwl) files for this drawing.
How can I get this drawing freed up from the lock that cannot be seen?
Thank you.
