If it is only happening on particular books then the language is probably specified incorrectly within the book, at the top of the text files, you should see something like this:
Code:
<?xml version='1.0' encoding='utf-8'?>
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
But, if the lang tags reference a language for which you don't have a dictionary (e.g. 'pl' for Polish) then you will get no spelling errors.
When I changed a book to this:
Code:
<?xml version='1.0' encoding='utf-8'?>
<html xmlns="http://www.w3.org/1999/xhtml" lang="pl" xml:lang="pl">
I was sort of surprised that I didn't get a message something like:
