Hi Charles

These are definitely comments - or at least the few I have started adding - and like all the others they toggle on and off with the Paragraph Show/ Hide button...

I don't think I have ever come across this before.

One thought that has struck me since my initial post - I'm not sure what version of Word this doc was produced in, but being a government doc, it's possible its an old 2007 or older version, and I'm wondering if these are somehow inline comments as opposed to the newer, normal Balloon comments.... did they used to hide with the toggle of the Paragraph show/hide button??

I'm not an expert on this, so could be way off the mark.
