When I try and modify the privacy statement in language editor (modifying an ES set in host with site selected), after hitting update it bombs with the message :-

A File Operation Failed. Please Check Resource File Permissions So Files Can Be Edited.

this does not happen when I edit any other fields in global.  I have tried pasting my version of the privacy statement (in Spanish) and just adding a space to the english text.  Both create the problem.

I am not seeing any message written to the log file.

This is in 4.4.1

Any thoughts?

But I can update other keys in the same resource file so I guess it's not due to the permissions (which I had checked and seem OK).  The resx file is also corrupted on output - the last 5 or 6 lines are missing.
