Remove threaded comment warning
It would be helpful if when trying to view threaded comments on an older version of excel, there wasn't a long warning shown every time.
Because of this, you cant just quickly hover to view the comment. You have to go in and format the comment box to make it much bigger in order to actually view the comment that follows the warning. This can be very time consuming. Would be better if the comment box was just made view only or a warning popped up only after you try to edit the text.
