Please , accept my apologies if it has already been reported ... Installed ESS v4.0.68 on XP SP3 Microsoft VM and the firewall is not working at all if used with Interactive , Learning , Policy-based , Automatic+rules modes . It works only in Automatic mode but nothing else . No application is allowed , no pop-ups , no nothing . Even tried creating rules manually , nothing . The VM setup is quite basic - just basic XP Home SP3 + VM add-ons + Firefox v3.0.4 + UPnP device host service disabled + SSDP discovery service disabled . Tried repair , still it is not working . I have no problem such problems on Vista .
