I have opened my current text, Eph 4:17ff, in both Lexham SGNT and Lexham Clausal Outlines of the NT. Both display hyperlinks to numbers that I am pretty certain are Louw-Nida numbers. The numbers are blue; when the mouse hovers over them, the cursor changes from an arrow to a pointing finger. But when I click the links, nothing happens. I suppose it's possible that these are meant to be tooltips, but if so, nothing is displayed.
