Strangely it gave me a tx ID of : d7fa70f6-26be-43a9-9c97-ee83f8d9d399
Never seen Tx Id with dashes
Blockchain info & Block explorer say Tx ID doesn't exist and the address in question shows no transaction being received. Blockchain.info is pretty good at showing even unconfirmed transactions. Note: this isn't a wallet issue the network is showing the transaction simply doesn't exist (nor is there any other transaction for the amount to the address).
On edit: 8 blocks (100 minutes) have passed and transaction is not on even unconfirmed on the network.
On edit edit: looks like for Mt Gox to Mt Gox transfers the transfer happens internally and later (much later ? ) rebalanced on the block chain.
Locking.
