When I turn on Japanese support in Word, that means that I want to enable features like vertical text and kanji grid spacing. It does not mean that I want to format all new documents for A4 paper.
While we’re on that subject, thank you for changing the Language Register application into something that you run in Office 2008, and no longer something that you drag other Office apps onto, as in previous versions. Also, thanks for no longer switching the input method from English to Kotoeri every time I launch Word; that was always a real pain in the ass.
