ERC20 explicitly says: Note Transfers of 0 values MUST be treated as normal transfers and fire the Transfer event. Yet, your code return false on 0 and do not call Transfer event. if (balances[ _from ] >= _value && allowed[_ from][msg.sender] >= _value && _ value > 0) { I guess, it is not fully ERC20 compatible then.
