When I try to use the 'Keys > Publish to Global Directory' PGP Global Directory assistant, it responds with:
'The server key for the PGP Global Directory could not be obtained.'
The last time I reported this, Tom replied that this happens rarely. ( https://www-secure.symantec.com/connect/forums/pgp-desktop-server-key-pgp-global-directory-could-not-be-obtained )
But since it happens consistently for me, then I submitted an 'improvement opportunity' where I rewrote the text for the 'currently empty' error box for you, in order to make it as easy as possible for you to implement.
I'm disappointed that six months later, nothing has changed. (PGP Desktop has changed from 10.1.1 to 10.2.1 in that time...) The revised text has not been added, and the error box is just as totally unhelpful as before.
Thank goodness that "Symantec Corporation is committed to product quality and satisfied customers."
