my bad, I wasn't aware there's a new wallet version already. I just update last night to 4.0.2, left it overnight to sync.
My wallet staking 24/7 so I dont know about newest version when I wake up and I check wallet 05/01 to vote I saw vote window and I vote for SeGwit but dont know about relase again newest wallet version.
And now I saw too: Warning: Unknown block versions being mined! It's possible unknown rules are in effect ...
