I may be mistaken, but Lexham English Septuagint no longer shows a text selection for the visual filter Corresponding words or selection when I select a word in LXX Swete (contains both Hebrew and Greek, is titled The Old Testament in Greek According to the Septuagint, is not the Lexham LXX Int Swete). I believe I used to be able to, and liked to use this Septuagint version that includes both Hebrew and Greek to use with the Corresponding words filter to bridge NASB95 and LES. LES I believe was recently updated with a reverse interlinear LESLXX.lbsrvi, may have something to do with a change of behavior?
Edit: Corresponding selection works as I remembered when I turn off Corresponding words visual filter, as I continue to work with these resources.
Further edit: I need to remember that a selection is a swipe, different from a click, and then I seem to be able to keep both Corresponding words and selection checked to get the behavior I expect.
Further edit: Something is not stable about the interaction of these Septuagint resources. I have crashed twice just now clicking on a word in LES with NASB95 the lead resource in multiview, with LXX Swete and DSSI also.
