It's entirely possible that something's ill defined in the FC management console (I din't do it - it's another guy's responsibility :) ) --------------enig3A8B66DB1C6B76E1AD10C28B Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.4 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFF8cd8ldnAQVacBcgRAluYAJwKRTfLzwg0ZVOHBFAQPfKzzWeqTACeMHbb T8u1rpDUTLpQCQY01aYy4VQ= =Oq7w -----END PGP SIGNATURE----- --------------enig3A8B66DB1C6B76E1AD10C28B--
