Thanks so much for your help. They were sent from my multi-bit wallet. The transaction has been showing 'seen by 1peer' for several day...
Don't really know what to do.
Many thanks
Gav
Actually I experienced something similar with Multibit a few days ago. I sent a small amount of bitcoins to one of my own addresses and noticed the transaction was only living in the multibit client but did not seem to be broadcasted properly. After resetting the Blockchain two times for all wallets and a few restarts of the client it finally forgot the transaction and showed the correct amounts and I could try again successfully.
You can reset your Blockchain using the "Tools" menu. It may take a while. Good luck!
Thanks for adding that info. I have no experience with Multibit, so I cannot help with it. Maybe others with Multibit experience can either chime in here or post links that Gav can use to help sort this out.
