Below is a small portion of the 200 KB Common Ancestor Report for the root node with XDb1 (v4.5.3) on a db without any user entered data. One can run the new exe version with existing dbs to verify that there were no changes to db structure (earlier exe version didn't pass the correct parameters to the report generator for root node).
