To clarify, I'm not concerned whether there is a nickname displayed or not. Just noticed that a nickname in quotes was the key difference to Pathfinder lookups that return a blank name and first line of address blank.
+ That's happening because the insertion of the nickname breaks Pathfinder's ability to extract the first name and address.
+ QRZ is certainly free to change their web page however and whenever they like, but the impression of apparent unreliability this evokes when one of their unannounced changes breaks Pathfinder -- particularly among new users -- is leading me to consider dropping "QRZ.com via Pathinder" as a callbook option in DXKeeper.
