This can normally not be, at least I've not seen such a behavior in the past years. The Thunderbird binary must detect at something that it is already running. So the key than would be to know what Thunderbird is detecting. > Even after restart of machine or attempt to kill any remaing > thunderbird process (that of course is none there). And if you have restarted the machine the only thing that than possible remains is some file stamp, but Thunderbird doesn't use such things except while working on your user profile. So I guess simply you have a lock file in your profile. http://kb.mozillazine.org/Profile_in_use#Remove_the_profile_lock_file > There simply is no thunderbird process runing, and yet the > Thunderbird claims there is. BTW: The above link I've found within seconds if I search for the string "Thunderbird already running" within the internet. :-) -- Regards Carsten Schoenert
