There is a new problem with FTM 2012 ver 18.104.22.1684
In Family view screen, if you select an offspring (son or daughter) and then go to the Person view screen and add or edit a Fact, then return to the Family view page, the offspring to whom you had just added/edited the Fact has suddenly become the Father of the family! Well, not actually. The edited offspring's Name, Birth and Death info appears in the left hand father's box of the parents. If you click on the Father in the Tree View at the top of the Family view screen, the correct Father magically reappears properly in left hand Father's box of the family. The bug was confirmed by FTM Tech Support today.
