Olaf,
> Well, there are very many words - almost all - that _shouldn't_ be written proper case within a sentence but only lower case, only at the beginning of a sentence thy are allowed proper case. So I would try to detect sentence ends (or starts) and only allow proper case there (as long as you don't add a new entry to the spelling word list).
I see your point, but in the text I read in English, I see many so-called lowercase words being capitalized in sentences for various reasons (emphasis, words used as names, etc)

Excellent point!
