This is not a LyX issue. However, the KOMA-Script web site is written in German, a language capability I lost several decades ago due to lack of use. What I seek is a resource to answer this question: Is there a way to use the fncychap package with the KOMA-Script book class?
When I try to compile the document I see this error: Class scrbook Error: undefined old font command '\rm'. If there's a way to address this I'd like to learn it. Otherwise, I would like a pointer to resources that show how to implement fancier-than-standard chapter headings in the book class. Rich
