File Name Length Problems and Offline Files

Offline files are still sensitive to long path names.  I had a Word document open (deep in a folder tree and a long file name) and tried to create a PDF for uploading to a customer.  I kept getting errors - sometimes it indicated the file was read-only (which didn't make sense) and sometimes it said I didn't have access.  Ends up if I shortened the file name a little, it would work.
