I re-installed ESS after a short break and found that access to a live chatroom driven by Flash was unavailable. I tied repairing Winsock with no joy. I uninstalled ESS and with neither AV or firewall installed was able to connect and see the message panes I installed NOD 32 and tried again - OK I then installed COMODO firewall and all was still OK. So - conclusion ESS Firewall element was blocking access. Why?
