Hi, Are there any known problems using ESS in combination with Thunderbird? Since I installed ESS I have problems with Thunderbird. It goes well for a period of time, but at some time I can 't receive or send mail. Message: "This folder is being processed. Please wait until processing is complete to get messages." When i shut down Thunderbird and restart it again, no problem. But after some time the same problem occurs. Already made a new profile in TB. Removed .msf files. Not helping. TB has permission of course in firewall settings. I uninstalled ESS now, and using NOD32 again. So far no problem the last couple of houres. Hope you understand what I mean.
