[GNC] Cannot write to file a new wrinkle

[Mahon Finbar]

Hello again,

After removing, renaming etc. the "offending file" as described, I now 
have a screen with 'unsaved book' which doesn't react to the 'close' option.

This appeared after a text box which said that the original offending 
file was not available, it was in the 'history' did I want to keep it, I 
said 'no' and then the screen I mentioned appeared.

I tried 'saving as' but it still won't go away.

Does anybody know what an 'unsaved book' is?

BTW, the same problem I have had all along (cannot save) is still there.
