Not sure why, but today my ESV Interlinear keeps disappearing (see below):

Now for the strangest part...If I toggle the Interlinear button off/on, an interlinear appears...but for a separate (NIV) study I'm doing of Nehemiah (see below). You can see I've given the word "Children" focus in Mark 7:27 in this example. Clicking around will make the Interlinear go blank again.
