The NASB has some "extra functionality" when the inline display is toggled the words turn into hyperlinks and are also click-able. None of the other RIs function this way.

These popups can get in the way ( http://community.logos.com/forums/p/21720/162769.aspx#162769 ). If I wanted (I don't) to see these tips I could enable the Strong's number line.
There have been oddities with Strong's numbers and search for some time. Is this related?
