If this fix is correct and can be done without breaking everything, can someone do it please ? -- Aurelien [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (FreeBSD) iD8DBQE+S9joDNsbHbt8ok8RAhiiAJ4ymdGkLFG+hpWLScRGR/3bLY/QYwCgpyQg wBOgude1/+eHlsLFTPh4uC8= =WbCd -----END PGP SIGNATURE-----
