(all components are in English by default)

1. Install the language pack from
http://extensions.services.openoffice.org/project/hu_dicts

2. Set the default language for documents in Writer to Hungarian.

3. Quit OOo. Start a new text document. Type a single word.

4. Set the following:
- Tools->Options->Languages->Default language = English (not just for the
current document)
- Tools->Language->For all Text->English
- Styles->Paragraph->Default->Font->Language = English
- Select all, Format->Character->Font->Language = English

5. As expected the language of the typed word will be set to English. But if you
hit a space, and type a new word, its language will be Hungarian, regardless of
the above settings.

6. Unless you uninstall the language pack, all typed words will be in Hungarian,
regardless of the language settings. This applies to all new documents as well.
Its not possible to write in English.
