I am assembling a master document out of existing documents. I successfully included a subdocument, which then appeared as part of the master. I made unrelated changes to the master, saved it and exited word.
When I attempted to reload the master, I got the message: "At least one subdocument or the master document is locked". However both master and subdocument are unprorected ("unrestricted access" in the "Protect Document" section of hte development tab.
In addition, the buttons Create, Insert etc in the "Show Documents" section of the Outlining tab are grayed out.
This happened once before. Closing and restarting word fixed the problem, but not this time. How do I get out of it?
