personal dictionary in OS X

Hi,

I’ve been using Language Tool for a few months and am no having difficulty with the personal dictionary in OS X Mail, it doesn’t seem to remember the personal dictionary on each new message. I keep having to reset it and it kind of works, but then when I start a new message, it no longer remembers the personal dictionary is there. The words in the personal dictionary are all saved, but it never applies to the actual messages.

Do you have any suggestions? Everything seems to be up to date. I think it used to work correctly, but perhaps some OS X updates changed it?

Thanks.
