wmd editor: how to surpress the html when in editing mode?

Question

Hi, I installed wmd in my application for editing my text area and it works good if I just want to look at the result:

proc print;
 var test;
run;

however, when I tried to edit the result, I got the following:

<pre><code>proc print;
 var test;
run;
</code></pre>

If there a simple way to get the same view as I created the text area withtout any html showing up?

thanks.
