To see what I mean open GNT28-T with the syntax in parallel. Search for the verse Matt 2:6 which is nested speech (NB). Roll the mouse over the text and you will see the highlighting in the syntax pane is off by one word. If you go to the previous verse or subsequent one cross highlighting is fine. And the syntax chart itself seems correctly aligned. Its just the cross highlighting from the text to the diagram that is off - going the other way (mouse over on the words in the syntax diagram) crosshighlights just fine.
