I've got the problem send the coins out using the windows wallet version 3.5.0
The send function is working fine at the wallet just open.
But after unlock the wallet for staking a while, tried to send the coins to Bittrex, it just no further reaction after the password was key in to confirm the sending. Wallet was still running and staking was working fine.
Does anyone encounter the problem? Or it just my wallet setting problem?
No I have exactly the same problem and i have reported it here.
The workarround is to quit the wallet and restart the wallet and THEN send the coins to Bittrex. No Idea why this happens but the devs are aware of the problem.
Hope this helps.
