[Dx4win] New entities

[F6EXV Paul]

  Hello all
After installing the latest version of the country file, and merging 
with my old one, I find that for example a QSO with PJ2MI in 1992 is 
still counted for the "new" entity of Curacao, and a QSO with PJ0J in 
1987 is still counted for the "new" entity of St Maarten.
It looks like the callsign mapping does not consider the start date of 
the (potential) new entities when callsigns are imported.
Is this a bug, or have I done something wrong ?
Thanks + 73
