[Dx4win] Export to LOTW problem

[Kelly Johnson]

I tried to export my recent QSOs for upload to LOTW today and had a
problem.  Here's what I did:
1) Filtered all QSO's with the UPLOAD flag set to N.  This yielded
only about 20 QSOs.
2) Selected "Export to LOTW", selected the file name, etc.  It
generated a .ADI file.

I editted the .ADI file and it had no QSOs in it.  It had a single
line header at the top of the file but no QSOs.  There should have
been about 20 QSOs.

I then went to the standard "Import/Export" menu and exported an ADIF
file there.  It generated a .ADI file, but this time it had the 20
QSOs I was expecting.  I ended up uploading this to LOTW, but the
upload date didn't get set right.  I ended up doing the upload date by
hand, but I still don't understand why the Import/Export menu worked,
but the "Export to LOTW" menu did not.  Anyone know?
