I'm running 4.2 SR-2 (4.20.4.8828).
Anyway...when I open up the interlinear function at the bottom of my preferred Bible the Louw-Nida option is inevitably missing. I need to click, then click, the select and it's back.
But then I do a new passage guide search or open my Bible to read it and then click interlinear we're back to no Louw-Nida.
For your consideration and feedback.
