This problem started a couple of days ago.
Whenever I try to "Save As" a document to our Windows file server (Windows Server 2003) Acrobat says "The file may be read-only, or another user may have it open. Please save the document with a different name or in a different folder."
I can save the document to my Mac desktop without any problems. I am running OS X 10.8.3.
Any ideas?
