Now it shows it also in the gui. Weird. It seems you have to close the client to make it show your votes when you vote the first time.

can you issue "wallet_account_vote_summary" in the console and check there?

I don't get any confirmation about which delegates I successfully voted for.

I did the following: I went to the Delegates list and made my thumbs up, then went to My Account > Vote and clicked "update vote". Nothing happened, no bts balance reduced (no transaction to myself ?) and no delegates in the list in Account > Vote > Current Votes.
I also manually transferred my whole stake to myself, which didn't give me a confirmation (by listing the delegates in the Account > Vote > Current votes list).

Any idea what the reasons are here?
