First, a big thank you to John for including this test in his Second Site software. As he notes there it is hard for TMG to recognize. Yes, Andrew, it is an aberration in TMG. In fact John was the one whose deductive work first found this condition in TMG v6 twelve years ago. It was very hard to replicate, and the most likely culprit was probably some strange condition when doing a set of merges. However, users do lots of merges and the creation of this condition is very, very rare. Again, thanks to John's software for testing for this. Michael
