I've carefully used new-lines to break up my directions into paragraphs. I feel this makes them easier to follow. The new-lines show correctly in the 'Directions' pane but are ignored when clicking a direction in the map to display it in a pop-up.
Also, the pop-up shows the text centred. At first sight, this looks tidy but makes nonsense if the directions contain a list which one would normall expect to see left-aligned.
Thanks for that feedback Martyn.
