Everything was fine with the program, and out of nowhere the Lyric Tool stopped working; I'm using the free download in Windows 10, and am writing a simple 69-measure SATB motet. I can go back and change notes just fine; I can also go back and edit lyrics already present, but about 30 measures into the second (between tenor and bass lines) layer of text it just stops. I have tried restarting Finale; I have tried rebooting the computer. I have double-checked to see that I was  using the Lyrics Tool. Surely there's a fix for this, but I'm stumped.
