A user asked, "Why is it that upon closing cross cross-section navigator, users have to re-associate an alignment, pick a viewport to display the dynamic cross sections, and then data point inside this viewport to get the Cross Section Navigator pop-up dialog box to show up again?" It would seem that maintaining the last alignment selected as the "active" alignment might save a few steps and button clicks. Create a "use active alignment" or similar association to avoid these repetetive steps.
