Problem with widgEditor for WordPress

I am using widgEditor for WordPress which I downloaded from http://davidgonz.com/archives/category/plugins/ .
But I can’t seem to get it to work.
I insertted the class=”widgEditor” in this line in my comments.php
<textarea name=”comment” id=”comment” class=”widgEditor” cols=”100%” rows=”10″ tabindex=”4″>

However things aren’t working.Only Opera seems to render it some what ok.
