Oh and not sure on the 'bug' claimed in Armoury preventing him from sending coins without confirming the previous transaction.

If you're sending them from a single wallet and there's a large amount of coins in your wallet it's your change coming back to you from the network, not a bug in armoury, because as far as the network is concerned you've got 0 until it hands you change after the confirmations are completed.

Or I'm completely wrong, and you do really have a bug that happens to be mimicking that behaviour, in which case - my bad.
