Since 0.4.6 I can not send coins with local wallet.
When I try, console goes black and I need a ctrl +c to re-start.
I recommend to join us at Slack.
I need to know:
1. Sum which you try to send.
2. What means "console goes black"? Without error?
3. What is your config.minerMinimalFee?
Try to update to last version using git pull.
