I just did that and something freaky happened. The outgoing transaction with 0 confirmations just disappeared and the BTC that was already debited went back into my total...? I've seen a 0 confirmation sit there for days but never go back into the wallet total.

There is no firewall on right now.

There is only one copy of bitcoin running.


If I send it again, is there a chance it will be sent twice now or not since the money went back into the wallet?

There are 129744 blocks showing on the laptop.
