I have been using Open Office for years and recently something changed on their spreadsheets.
I assume it was me, who did something unknowingly.
Suddenly some of the boxes on my spreadsheets have a red border and changing the content does not always work.
I have attached a pic.
And if I move the cursor over one of these boxes, a new box appears telling me in what way I changed that box recently.
If anybody could help me to get rid of these red lines and everything that is attached to that, I would be very grateful and happy.
