Hi Jonathan, This looks like the same issue that I contacted you about in the following message from September (originally reported by Defacto <gdef@cvd.pl>). Message-ID: <20020925132524.GH82779@hellblazer.nectar.cc> Message-ID: <20020923143811.14F8D13FB09@cvd.pl> I can resend if you like. Just hoping to help you connect the dots. Cheers, -- Jacques A.
