I have a separate group for each of my (4) grandparents. Each group contains the grandparent, all their ancestors and all their cousins. Until recently all I needed to do to update each group was to select the individual grandparent, then do the following actions:
Ancestors of highlighted person
Ancestors and all collateral lines
Then press OK
In two of the grandparents' groups by doing the above everyone in the database becomes selected, but the other two groups work fine.
I have done the four database tools tests (this has happened in the past and I found that rebuilding the index cleared it).
The problem occurs on another computer. So obviously I have created a wrong link somewhere and I wonder if anyone has any tips as to how I can find where I have gone wrong.
