Thanks Kouye

This has been a big help with my understanding as to what is going on "under the hood". When I encrypt a wallet, the warning message that comes up but doesn't help much, is a warning that old copies of the same wallet could be used to steal your coins. I don't understand how two wallets with the same public address can show different numbers of transactions but you can't argue with the Blockchain so just check the address in there.

I will permanently retire the incorrect wallet and put a password on the one that is showing the correct transactions.

Thanks for all your help
