Using Thunderbird 126.96.36.199 several received msgs are marked "[spam]" at the beginning of the subject line. To teach the program, I go to the "messages" drop down from the toolbar and there is "Eset Smart Security" with an arrow pointing to the right. There I can choose "not spam." Then another window opens reading "reclassify selected message(s) as spam," etc., with yes or no buttons. This dropdown opens behind the TB "Messages" dropdown and only a quarter inch of the left side can be seen which is sufficient to drag it into view. (Even though the Eset popup is formatted to be in the foreground, it is in the background -- this is apparent because I have header bars which if in the foreground are green and if in the background are red.) Need a small correction here that will correct this activity.
