Xtreme and Web Designer now offer Spell Checker. In several different
languages including two flavors of English and three versions of German.
Select Check Spelling as You Type and your language of choice. If you
are using foreign words you can check those too. However it is not all
that easy. You have to specify another language, then lie and say this is
the default language. Then lie again and switch back to your native
dictionary. You can also add words to your dictionary.
