I've discovered that AJAX Comments 2.0 stops working properly if you have ShowOnFrontPage plugin (v0.3.1) installed.
And we got another report, that it also stops, when you have SpamKarma activated.
We are working on a solution.
Open comments.php from your /themes directory and use the following code (mostly just the ids) for AuthImage to appear in your comments form:
<?php if ( !$user_ID ) : ?>
<p><img id="auth-image" src="<?php echo get_option('siteurl'); ?>/wp-content/plugins/authimage/authimage-inc/image.veriword.php" alt="Verification Image" /></p>
<p><label for="code">Word Verification (<a href="#" onclick="document.getElementById('auth-image').src+='?'+Math.random();return false" title="Generate another Captcha Word Verification image.">can't read it? try another!</a>)</label></p>
<p>Please type the letters you see in the picture.</p>
<p><input name="code" id="code" type="text" class="text" tabindex="5" /></p>
<?php endif; ?>
