yup, try this conditional
PHP Code:
<if condition="THIS_SCRIPT != 'private'">
// template code that should only appear on posts and not in PM
</if>
alternatively:
PHP Code:
<if condition="THIS_SCRIPT == 'private'">
// template code that should only appear on PMs and not on posts.
</if>
So I'm guessing that the new hybrid reply button should be encapsulated in the != private bit as follows.
PHP Code:
<if condition="THIS_SCRIPT != 'private'"><if condition="$post['replylink']">
<a href="newreply.php?$session[sessionurl]do=newreply&noquote=1&p=$post[postid]"><img src="$stylevar[imgdir_button]/reply_small.gif" alt="Reply" border="0" /></a>
</if></if>
