I've recently started to use the "AJAX for post editing", the problem with this is that when I try yo preview the message (through the button), I can't see anything. The window opens, but it tells that there is nothing written and this is not true. I don't have this problem when I edit the message from the "advance editor (or old editor)".

Am I the only who has this problem?
