When adding a NEW person to the database from the add children or add parents windows, the new person keeps the focus when returning to the add child/parent window. It is then just a matter of clicking <OK> and the new person has been added as a child or parent.
When doing the same for a spouse, the focus is lost when returning from the New Person window to the Add Spouse window. It is then necessary to search through the list for the person I have just added before I can choose <OK> and add the person as a spouse.
Matching the spouse window behaviour to the children and parents windows will be consistent and easier when adding spouses (is that: spice ;-)
