Thanks to the people who checked for duplicate ID numbers and did not find a software problem.
I did go to the "Sample" data base. Checked for duplicate ID numbers and none found. Went to the customize option and used the option to clear all ID numbers, none found. Used the option to use the prefix JMI and the RIN number to set ID numbers for all. 220 set. Used the "clear all", says cleared 160! Set the ID numbers again, the same way, says 160 set. Cleared again, 160 cleared. Name list says contains 160 individuals Ran the merge duplicate ID numbers again, none found. The 220 set, 160 cleared, 160 set, 160 cleared indicates there is a software problem. Would appreciate it if some of you would try this on the Sample data base. I am beginning to suspect that I may have a "bad" Legacy usr file or something. I Tried this on an old Legacy 7.5 file and had similar results as for the Legacy 8 Sample file. 62,168 Individuals in file 50,837 duplicate ID numbers 61,503 cleared (all) 84,620 set (all) 62,168 cleared Last 2 steps repeated Jay Ingalls Legacy User Group guidelines: http://www.LegacyFamilyTree.com/Etiquette.asp Archived messages after Nov. 21 2009: http://www.mail-archive.com/legacyusergroup@legacyusers.com/ Archived messages from old mail server - before Nov. 21 2009: http://www.mail-archive.com/legacyusergroup@legacyfamilytree.com/ Online technical support: http://www.LegacyFamilyTree.com/Help.asp Follow Legacy on Facebook (http://www.facebook.com/LegacyFamilyTree) and on our blog (http://news.LegacyFamilyTree.com).
