Because the Finney I mine go away every time I start alethzero, I thought that by creating a new address and send the money there I would save some.
So, I created the new address, I saw it in my "Owned Accounts" area, then in the area above called "Transact" I put the new address in the To field, then 1000 Finney, and clicked Send. Nothing happened. Then I said maybe I should write something in the Data field, so I wrote "Donation". then it crashed. this is the error:
terminate called after throwing an instance of 'boost::exception_detail::clone_impl >'
what(): Unexpected character encountered in input.
