I think preview quit working correctly when the up/down voting arrows were added.

Have you two let SuperG know?

He's not psychic. He can't fix problems if he doesn't know they exist.

Preview works fine. But you can't post after you preview - the POST button on the Preview page does not work.

But you can copy your text after you Preview, hit the back button, paste, and then Post.

I've emailed support with the comments above.
