[Dx4win] Importing Dupes

[Art - W6KY]

Is there a check box that I am missing that allows DX4WIN to
import dupes???  I am trying to import a state QSO party where
mobile stations sit on county lines. You might have 10 QSO's
with the same station/same band/same mode, but different
counties. 
DX4WIN basically blows up on importing an ADIF file that has
dupes. This is not good. I saw this in the past but thought it
had been fixed.
In some contest (Sprints) it is recommended to work dupes as
they will count as zero anyway. The time it takes to explain to
someone where you worked them and what time can loose
you the contest...
Tnx es 73, Art  W6KY
