I have been searching the forum and I can not find a solid answer to this question:  Is there a way that anyone can stop a transaction before the confirmations have been made.  For example; I pay Joe Dip 1.1 BTC for a domain name.  I can see that the transaction is waiting confirmation in the block chain, however there are no confirmations yet.  The seller can also see that the transaction is waiting for confirmations to come through.  Once we are at this point is there anyway that I could stop the transaction?
