Unusual Problem with comments

1] I am using the blue-zinfandel-3column theme. The comment box on my blog was too large. So, I edited template file comments.php and uploaded it to server. Here is how it looks now:

<textarea name=”comment” id=”comment” cols=”40″ rows=”10″ tabindex=”4″>
</textarea>

When I view the source code of any post the textarea is shown as
<textarea name=”comment” id=”comment” cols=”100%” rows=”10″ tabindex=”4″></textarea>

How come its showing cols=”100%” and NOT cols=”40″?

2] Next, I modified CSS properties for textarea and for all comments section. Still the same problem.

3] Next, I deleted comments.php from server and uploaded it again. The problem persists. The source code still shows

<textarea name=”comment” id=”comment” cols=”100%” rows=”10″ tabindex=”4″></textarea>

4] Now, the bad thing. I deleted comments.php from the theme folder and yet the comment section is visible on blog posts and still shows:

<textarea name=”comment” id=”comment” cols=”100%” rows=”10″ tabindex=”4″></textarea>

I have tried everthing … I am not getting frustrated … why is it still showing cols=”100%”?

Please help!
