I've noticed this for a while, but assumed it was temporary and would be fixed. It's been months now and the problem persists. I don't know if it is limited to Safari or my settings, as I have never tested it with other browsers.
When typing a new post, reply, private message, etc, the "Preview" button doesn't work properly. For example, if I press it while typing this post, a new "NA" window appears with nothing inside but the "Close" button. I just tested it while writing a PM, and some sort of default instructions on how to write a PM appeared (talked about Chubby Cherub and such).
Preview worked a year or so ago. Am I the only one who has this problem?
