I tried to send 9 DRK using DarkSend this morning. The GUI went gray for about 3 minutes. Then it showed one transaction, "Payment to yourself" for 0.093 DRK. No transaction for 9 DRK ever appeared anywhere, nor was my wallet balance reduced by 9 DRK. What went wrong? A little later I sent 51 DRK not using DarkSend and that transaction went through normally.
