Many thanks - that was exactly the problem. One thing I did find; when I accidently set it with the \ key, highlighted the notes and went to Notes / Colours it still had Default ticked. I then right clicked and went to Properties - which showed them with the colour and allowed me to re-set. But when I turned it on with the menu it showed correctly in the Notes / Colour menu. Hmm. I must be more careful with my little finger! Again many thanks to all.
Hi. Several times now, and in different files, while just entering new notes in a bar, they turn red. I've looked very carefully and can't seem to find any reason why. Any ideas?
