When I open Eph 4:19 in the ESV and right-click the word callous I see a list of Greek lexicons and can select the one I want. If I double-click the word, however, it opens up BDB. Others behave in different ways. Double-clicking practice opens up BDAG. Double-click every opens the exegetical dictionary.
What governs Logos' choice of which resource to open? I have BDAG at the top of my Prioritize list and at any rate can't understand why BDB would ever open for a Greek-tagged word.
