Good Morning, all ...
To bring you up to date on this, yesterday I started thinking about simply adding those 3 indexes to the CreekTree database to see what happens, so I enabled user tracking again ... and found that it was working again! The database still shows no index for the table but I can't find any discrepancy in how it operates.
So I'm in a 'leave well enough alone situation' unless someone has any idea what could have caused the malfunction, and what could have happened to those 3 indexes. Would appreciate any thoughts, comments, observations, advise anyone can offer.

Thanks,
