Hi Math, thx for your answer. The problem was caused, because i have imported an lectora online project in lectora inspire 17. I have noticed that often when i open online projectfiles in inspire, there exist font formating or position problems (wrong font and wrong postion of textboxes). i solved this with Tims advice ([Ctrl]+x and reinsert unformatted [Ctrl] +[Shift] + v). My old texboxes i have deleted and made new one.
