I'm using the bitcoin-qt client on v0.8.1-beta on Mac OSX
I have 3 addresses. I tried sending .01BTC from one address to another.
1K3BjT1y2X2v3PGhqHh33dRb6kVGdR5CBA -> 1MattHdtuFSof3ctrZhTGzsfQecQBso2nw
However!!! When I lookup the transaction ID: f638b5ecda8d8b0280a49f342e6cac13560917d5e678f1e3b9a7f35f69b15b97
I did sent the .01 to myself but it also sent 1.2594786 BTC -> 1Ypzoqn4BYSbgeqPJ3mSPdqBC8JGzgX4r
I have no idea what the 1Yp... address is!!
What happened!!! Did I just loose $1000 ?
it did NOT prompt me about paying any transaction fees!!
I would greatly appreciate any help!
Update: Yeah!!! I recovered my coins. For whatever reason bitcoin-qt generated a new private key but didn't show ANY indication of this in the GUI. This may be because it was backlogged by about 100 days in downloading transactions.. not sure. but in any event LUCKILY i had been messing around with trying to migrate to multibit.. anyway i tried to export the private key and was successful:
walletpassphrase 120 dumporivkey 1Ypzoqn4BYSbgeqPJ3mSPdqBC8JGzgX4r
Then it worked ! it actually dumped the priv key and I was able to import into blockchain.info and get access again. Not sure what happened but it was very unnerving... again, the GUI does NOT show 1Ypzoqn4BYSbgeqPJ3mSPdqBC8JGzgX4r as one of my addresses...
Anyone care to explain what happened?
