Drawings in read only mode

Drawings are created nomally.  Parts brought in, assemblies brought in, parts labled, dimensions added etc.  I use a "D" sized customized template with my company name and drawing name in lower right corner.  When I complete the drawing I do a "save as", name the drawing and close it out.

When the drawing is brought back in for editing, all of the options are not available, including opening other drawings or parts.  That drawing has to be closed out before I can do anything else.  I have checked file properties and everywhere else I can think of.  This has happened on multiple drawings, but not all.  Any Ideas?
