Is this a New Youtube Updates?

Today when i started to post comments in some youtube videos, it asking for "sign in". I already sign in to that account, but it keep asking always when i try to post comment in any videos.

I can easily post comment on any channel, no problem on that, i can send friend request also.

And also i noticed that from last 3 to 4 days, youtube hangs my machines, some times it crashes also. Initially it asking for adobe flash player updates, i already update that, but still it slow down the machine huge and hangs after sending 20 to 30 friend request.

Is any one know abt this?

what happened?

Same here man,YT force me to the login page even I am logged in.

Works for me atleast with my personal Gmail/yt account...

Maybe its the accounts

do any one face this problem? can you guys post comments in videos now??

Well I can't login to any of my accounts with my commenting software... guess yt found a way how to stop software commenters.. :/

do any other member facing this problem?? i m on 3rd day, still i can not post comments on youtube videos. I have tried from 10 different youtube accounts with 10 different private proxy.

I can send friend request and post comments on channel.
