TDBAdvGrid problem

Record posts when changing focus to another field after editing a field on same row with EditPostMode set to epRow.  Why?  Seems to cause Record Not Found on Resync with client data set. 

I cannot reproduce this here. When setting in the ADOEditing demo for TDBAdvGrid EditPostMode = epRow, I don't see a post happening when changing the DB field within a record. How exactly can this be reproduced?
