I still have a blue box & narrator has been turned off since February when I first had the issue. I went back in & turned it on & off again as well as the keyboard shortcut & have restarted the computer multiple times. The blue box still apears on everything I do even though the program shows that it's turned completely off. I have Windows 11.
