When I'm typing something and I use a word that is not in the
dictionary, the word gets a squiggly line underneath it. In the past
I could right click on that word and a box would come up letting me
change it to a recommended word or give me the option to "add" it to
the dictionary.

Now that "add" feature is no longer there. I can see it, but it isn't
clickable. Did I do something to eliminate it? How do I get it
back?

Thanks.
