For the first time I have found a workable Latin spell check.  I take a lot of notes in Latin and type very poorly.  This tool seems to do the trick.  In Word, you need to make sure that it is an option, and then select the text for the language by hitting control-a.  But then it works marvelously.  You need to go into the program to make it deal correctly with I, j, v, u, etc.  The link is here:  http://drouizig.org/index.php/en/binviou-en/correttore-ortografico-di-latino/250-en-col-latin-spellchecker
