...highlight colors are blank (all white).
Uhmm, I may not be able to read/speak French, but I beg to differ with your comment. According to your screen shot, there are exactly eight colors available for use in your System.
You had the "Blue" dot selected when you took the screenshot:
"Couleur d'accentuation:" shows the left-most color 'dot' selected.
"Couleur de surbrillance:" shows what any highlighted text would have as a background color; "Graphite".
I still do not see the requested screen shot I posted in my last post:
"1. Please send a screenshot and the name of the app in use at that time."
That would allow us to see more of what you are seeing on your screen.
Suggestion [
three steps]:
1. Select a different "color dot", the fourth one from the left (Red). Now,
2. select some editable text and
3. send us a screen shot of that area of the screen. Show us the selected text
AND the text above, below and to each side of the selection. In other words, select an area that includes a selected word (or two) and include a line of text above and below as well as a word of two on either side of that selected word.
Please see the image below. It shows a word (Show) highlighted within some text in several lines of
UN-selected text.
Thanks!
