I had this same problem on my board. Though I'm not using your hack at the moment, I've created my own long ago in 3.0.7 for my hack system. When I had this problem, it was caused by a condition I was using. This was the condition.

<if condition="$forum[ishack] == 1 AND $post[postid] == $GLOBALS['FIRSTPOSTID']">
&nbsp
<else />
<!-- the rest of the postbit template here -->
</if>

I don't know if you using a simalar condtion, but that will grab the first post and hide it. The only problem is, that will grab the first post on everypage...

The only way I was able to fix this was to create a query that grabed the firstpostid out from the thread table.

Hope this helps you out some. I havn't used your hack yet, But I do plan on using it for my upgraded version of my hack install system.
