No. I had 9 ZeroVert. Pressed mint (+entered password), waited until I received the long TX, pressed spend (+entered password) and waited again until I received it and repeated the whole process for all of them.

I was patient and don't think I could even press spend immediately after minting because the wallet hangs as soon as you press one of the buttons.

Looking at the debug file: "2014-11-17 10:02:47 ERROR: CTransaction::CheckTransaction() : COIN SPEND TX DID NOT VERIFY!" And I only see one long TX over and over. Cheers
