I'm facing a recurring bug where I enter a discussion (mainly from Google) and then none of the commands (vote up, comment, add a response) works. They just don't work. No message error, no client inconsistency.
I've just tried to add a comment to one of my posts and needed to do it 3 times before it works ok.
Here is a screenshot with some console output and the state of the site:
I'm using Windows 7 with Chrome 19.0.1084.56.
