I had trouble sending a transaction, as the Send! button didn't seem to respond. The first time I got a message my transaction fee was insufficient, yet when I agreed to a higher one .... nothing, no response at all. Cancelling the transaction and trying again didn't work, restarting Armory didn't work.

However, a minute later it did get trough. This was right after a new block was found. Just a few minutes before this transaction, I sent the same amount (0.1 out of 0.35) to a new address from a previously restored paper wallet, in effect sending it to itself. Only after this transaction got it's first confirmation was I able to send the second one.
