Does toggling again make a difference? When the files come in they may not obey the order and the toggle might pull them into the sort.
BTW, I wasn't being sarcastic, but on rereading my own post, I think it may come across that way unintentionally.
No difference... and no you didn't come across as sarcastic. In fact when I read your post I thought maybe I didn't make myself clear enough.
Anyway... I've got the system backed up now so I'm going to try a few things to see if I can resolve this. Perhaps the problem exists as a result of going from Beta 4.1 to V1.0
