neilo, use the stripslashes() function, it works for me.
open WUAE_yourfile_1.php, at the bottom of the file, add the stripslashes() function. see the example below:
before:
$MailBody = $MailBody . ((isset($_POST["message"]))?$_POST["message"]:"");
after:
$MailBody = $MailBody . stripslashes((isset($_POST["message"]))?$_POST["message"]:"");
