[Dx4win] New problem with Ext data

[Ruddy Dettmaring]

have putted in the webside Callsign lookup follow adress:
http://www.qrz.com/db/ <http://www.qrz.com/db/%3ccallsign> <callsign> (Setup
Parameters - Ext data)

When I push F3 and than "Enter" if have a link to qrz.com but also with the
failure: The search for "/db/%20FT5GA" produced no results.

%20FT5GA does not appear to be a valid callsign.

What do I wrong?

Has someone experience with it?

Thanks for advice
