[Dx4win] QSL manager updates

[Larry Benko]

I just spent the past several hours messing with the QSL manager
updates provided graciously by Vlad, UA6JD.  I don't know if
everyone except me is aware of a small shortcoming in the update
process but here is what I found with DX4WIN ver. 5.03.

Callsign HC8N had AA5BT for a qsl manager but now has W5UE.  If the
original QSL manager database has the field "HC8N,,AA5BT", then
importing the field "HC8N,,W5UE" will not override the original QSL
manager.  However if the imported field was "HC8N,23/04/2002,W5UE"
then both the early QSL manager and the current QSL manager show in
the database.  I would rather have both managers in the database
for obvious reasons such as outstanding QSL cards that may have been 
sent to the old QSL manager.  It appears as if a blank in the
effective date field is treated as the earliest possible date and
importing another QSL manager again with the earliest possible date
causes the import algorithm not to override the original manager.
Am I missing something here?
