PAILLARD, did you do a manual update to 38.3.0?
(In reply to Wayne Mery (:wsmwk, use Needinfo for questions) from comment #1) > PAILLARD, did you do a manual update to 38.3.0? Yes i did ! We have the same problem on 3 different computers of our network (2 on xp , 1 on seven pro)... the other ones haven't any problem (not update).
Sounds like maybe it was an addon. Had you tried safe mode? https://support.mozilla.org/en-US/kb/safe-mode-thunderbird And do you still see this problem?
Resolved per whiteboard
