tcp_ecn suggestion: i still get the same message running ``strace gnumeric'' with either ``net.ipv4.tcp_ecn = 0'' or ``net.ipv4.tcp_ecn = 1'' appended to /etc/sysctl.conf and running ``sysctl -p'' after static ip suggestion: i disabled the network and gnumeric started without any problem i don't know how to get my ip address statically on that dhcp configured network (if possible) any other ideas? thanks and regards, gabriel
