The editing window has two modes: source and visual. You may be referring to visual mode, which is the default when you first create a new article. It's only empty as long as you don't write anything in it. You can switch freely between source and visual mode, and whatever text you enter in one should be carried over to the other.

There is no preview mode, though there is a preview button (to the right of the editing field). If you click it, you'll see if the code you've entered produces the result you want. It shouldn't be empty unless you haven't written anything yet.
