cjk-Pinyin-Bug

[Karl Linek]

Hello,

I'm using Chinese characters an the pinyin-package as well. It works
well unless I make a second section in the text. The cjk-environment
always ends after the first section. It is not possible to copy and past
the text into the environment. Still it end after the first section. I
tried to remove the cjk-environment and to start it again. No success.

I'm using LyX 2.0.6. The OS is Ubuntu. 

This is the preamble:
\usepackage [notextcomp,oldstylenums] {kpfonts}
\usepackage {caption}
\DeclareCaptionLabelSeparator{colonenskip}{:\enskip{}}
\captionsetup [figure]
{name=Abb.,font={sf,footnotesize},labelfont=bf,labelsep=colonenskip,singlelinecheck=false,justification=RaggedRight
 }
\captionsetup [table]
{name=Tab.,font={sf,small},labelfont=bf,labelsep=colonenskip,singlelinecheck=false,justification=RaggedRight}

\usepackage{microtype}
