Outlook 2003 won’t spell check

I’ve got an Inspiron laptop with Office 2003 installed. Whenever I create an email with a signature, spell check will not work. I deliberately misspell a word to see if spell check catches it and it doesn’t.

I created the signature using outlook first then did an advanced edit and added three pictures: a header, signature, and a footer.

The only message I get is the spell checker saying that the spell check is complete (misspelled words and all).

I’m thinking about reinstalling Office. Any help would be greatly appreciated!!!.
