Whenever I am reviewing the close votes on the main site, I often (perhaps always) encounter the issue that I am unable to upvote comments to the question from the review screen, but have to open up the question in a separate tab. I am still able to add new comments, but often someone has said all that needs to be said. I don't like casting close votes unless it is clear to the asker why I have done this, so I like to make sure that I upvote any relevant comments, which gets quite annoying when I have to open tabs for several questions in a row.
Is anyone else having this issue? I am running chrome on windows seven if it makes a difference.
