I have a Windows computer loaded with Logos 7.19.
I own the Morphology Charts feature but when I specify a lemma and click the arrow, the charts will not load.
I saw the exact same bug reported in another post for Logos 8 (post and link below). The screen shot posted there is identical to what I am seeing. There does not seem to be a fix yet for that post.
BUG: Morphology Charts provided no results (WIN 8.3 RC 1 (8.3.0.0019))
