In every update of the ESS, it's a bug fix related to Thunderbird. How come? How come ESS has a such "big" problem dealing with Thunderbird? I don't think I have seen any other antivirus+firewall solution out there that have problem with the Thunderbird. Can't you make a firewall that has another way to work when it comes to the Thunderbird? Just to let you know, I haven't had any problems with it. By the way, great work. Terrific software!
