I lost the spell checker function. There appear to be several complicated fixes beyond me. This is important to a bad speller/ typer.
Going to 'Tools - Spelling' no language appears at the top so check shows no results. The tile labeled 'Confirmation' has to be answered in order to proceed at which point a language can be added, but when option 'Close' is selected appears  the newly inserted language choice is lost. 
Going to Spelling again, it begins with no language appearing and the whole fruitless thing is repeated. 
There seems a problem with the order of executions. It currently is;
Spelling (no language, no results) - choice - (then when closed) - add a language option occurs- close- and new language is dumped
I suggest order should be-
Spelling - select language if blank - choice - close. and language selection is retained.

Something elswhere is losing user language choice and user can't get it back which is super frustrating! 

The spell checker is super important to pretty well all users and a lot on forums are disatisfied. 
I don't know where user language selection is getting lost but there needs to be a way to get it back if it does go awal. 
Thanks for your attention.
