Hello,

A simple statement (Print) that I had highlighted in yellow (i.e., changed the background color) was changed into the garble below, for an unknown reason. In words, the highlighting was converted to a text-based description of the highlighting. I have been working on this notebook for days and it happened only now.

Suggestions for how to undo and avoid it are most welcome.

Best regards,

L J A Nilsson
