I am a new user of LyX and I'm confused about something: the User's Manual is formatted as scrbook, but when I go to the Document>Settings window, LyX says scrbook (as well as most of the other layouts) is unavailable. I'm confused about this, since it appears that the scrbook.layout file is in the layout folder. Why isn't LyX registering the fact that it has scrbook (and all the other layouts, too)? Any help would be appreciated.
Sincerely, Dan Kaplan
