On two macs my osx client v.1.2.1 wont launch after loading the chain when I click the button to open my wallet it says dcr wallet closed due to an error. Check dcrwallet logs and contact support if the issue persists. It does this with one wallet I am mining to that has always worked with a substantial balance, and one new installation on a different mac. Any idea whats wrong and how i can fix it? Thanks much, Seth
