I am new here and things here are still new for me. My friend got in trouble in posting a new question. He is new here too. And when he wanted to edit a quesiton, we found that nothing was showed in the preview window in his computer. Instead, it works well in my computer. So I want to ask for some help to solve his problem. I have tried to check the Javascript setting. But it seems that it has nothing to do with that. And what's more, no matter what we typed in the input box, even some letters, nothing appeared in the preview window.
Thank you in advanced.
PS:We have tried to use two different browsers, which includes IE and another IE-liked one. But I haven't try Chrome and Firefox. I don't know if this is the point of the problem.
