Can somebody please comment on this ? This may be obvious, but 8.1 is long unsupported. 8.4 just expired a few months ago as well. The knowledge of 8.1 is going to be pretty low at this point. You should try using a newer release to see if you still have the problem. 8.1 -> 8.4 is a pretty safe upgrade if you can manage it and have reasons to not go to 9 or 10. --=20 Regards, Bryan Drewery --NxnAujICcIq68KTFi4cIsBEDrPmEsECup Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBAgAGBQJWBCm7AAoJEDXXcbtuRpfPOvIH/2Kpbs9AuQywZCI4NenrfE+K 1UIT5fJK1SzAEn5afGsoGOrkVuKtifa4ykXam/2I97fvyeUJVhFj/O0f+5Dywud8 PdIFeG+Z6aWes/AjPqpESei2VwAlxmTsyHK8cQCPWGvn+KhBTCqYdNEWUu4YkN7E 9en+X/RVgq02hTBnteNtCoiq1FhVNqk6OBx4PxKYZcub9fRL/7z+8oCCVAZED4rJ srNWPADbQ4JyEE2F0odoKqoaS/ArOVR6tx3ce6Y3GkBfipEpbOc20FWYw5EqVoGY nNhPWgSiuT7O4kxa/x3sFo5g+3cvxFvg79dB4ET7nmwIrjqVbLPZ0lm8Vi8zhZc= =eP3t -----END PGP SIGNATURE----- --NxnAujICcIq68KTFi4cIsBEDrPmEsECup--
