unable to paste inside updated post editor

Q: I cannot paste inside the post editor, What to do?

A: When you have reached the bottom of the barrel, go back to first principles.
There is another way to paste inside the post editor (other than using right click mouse or CTRL keys).

Using your menu bar, edit/copy your text. Leave your cursor flashing inside the post editor, left click mouse on edit/paste. All your text will suddenly appear inside your post editor! Publish post.
