When typing a document and a word gets underlined in red, half the time I see 'Add to Dictionary' greyed out. Even when it is working, the same word is underlined in red when I go on to type a fresh document - and that occurs when I restart the PC, too. As you can imagine, this is driving me nuts.
CUSTOM.DIC is already ticked so that's not the problem.
If you have the custom dictionary set to something other than All Languages then Word only lets you add words that are in the language you specified. In other words, if you set the language in step 6 to French, then you won't be able to add any words that are in English, German, Spanish, or some other language. You can always set up multiple custom dictionaries and make sure that each of them is configured to the different languages in which you are working.
It IS set to All Languages, so that's ok, right?
That's how mind is set by default.
