I am a recent user of QT wallet and have some issues that may be resolved using the 'wallet repair' options. My wallet is encrypted by default during (re)start. Initiating most of the wallet repair options, after unlocking the wallet first, initiate application to restart. E.g. trying the first option ("salvage wallet") in the wallet repair page result in a pop up with the warning text: "Wallet is locked. can't replenish keypool! Automatic backups and mixing are disabled, please unlock your wallet to replenish keypool". This seems a bug that frustrates the intended action(s). Any views on this? I am currently using QT Wallet using Dash Core 0.12.1.1.
