umm, I'm on v1.5 and having some new issues. I didn't have my wallet encrypted before, so I didn't have to worry about unlocking it for minting. After upgrading, I encrypted wallet, and I tried to use the button on the front page to unlock wallet. The password was accepted and the button now says "Lock Wallet", however I am still seeing a message at the bottom left saying that minting is suspended because of a locked wallet. So, I went to console and tried walletpassphrase, and it told me that wallet is already unlocked. So, it seems like it is unlocked, but the message just isn't going away at the bottom left...
