I was used that, when I voted to close a question shown in the "close" tab of the review page, the question was then shown collapsed, and to the title was added a string saying the number of votes still needed, or "[closed]." Now, it doesn't happen anymore.
I voted to close a question that already had four votes, and this is what I see after my vote:
If I refresh the page, the question simply disappears from the list.
If this makes any difference, I am using Safari 5.1.2. on Mac OS X 10.7.2. The current SE revision for the site where I notice this is 2011.12.13.1.
