[NTLDR]

In newreply.php

Replace:

PHP Code:

    if ($postinfo[title]!="") {
      $title="Re: ".unhtmlspecialchars($postinfo[title]);
    } 


With:

PHP Code:

    if (strpos($postinfo[title], "Re:") {
        $title=unhtmlspecialchars($postinfo[title]);
    } elseif ($postinfo[title]!="") {
      $title="Re: ".unhtmlspecialchars($postinfo[title]);
    } 


Untested but it should work.
