I checked a GEDCOM which was exported from Legacy and compared it to the one I exported from GenoPro.
This is from Legacy:
And this is from GenoPro:
0 @marr00012@ Marriage1 TYPE Religious1 DATE 12 DEC 2000
You can see the differences where the Marriage date is. In Legacy it is under the Tag 1 MARR and then 2 DATE and 2 PLAC. While in GenoPro theres only 1 DATE. I guess that Legacy is searching in the Import for the same tags and can't find them.
Most of the GEDCOMs I saw had the pattern the Legacy produces, but, unfortunatelly, the GEDCOM protocol gives the programmer a lot of free space to play with those tags.
I guess that Dan will solve this little problem...
