I'll have to pay more attention the next time, as there are actually two 
sides to my issue.  As an example, I pay my credit card bill online from 
my checking account.  Each bank downloads the transaction as a payment 
(one incoming, one outgoing) and when I get the first one (whichever of 
those accounts I update first) I change it from a regular payment to a 
transfer, which creates the matching split in the other account.  I 
thought (but may well be wrong) that if that transaction downloads 
again, it doesn't find the transfer as a duplicate.  However, it's quite 
possible that I'm confusing this with downloading the transaction for 
the other account, it doesn't match (which I know is different from 
duplicate detection.)   This does not happen with "normal" transactions, 
only ones I change to transfers,  I suppose it just shows that someone 
who has used this software for over ten years can still get confused at 
times about details.
