[XeTeX] Counter reset problem

[Karljurgen Feuerherm]

Hello all,
 
I have set up a counter and environment (using XeLaTeX) as follows:
 
\newcounter{examples}[chapter]
 
\newenvironment{examples}
 {\begin{list}%
  {\textsc{Example} \arabic{examples}.} %
  {\setlength{\labelsep}{10pt} %
   \setlength{\itemindent}{10pt} %
   \setlength{\leftmargin}{0pt} %
   \setlength{\labelwidth}{0pt} %
   \usecounter{examples}%
  } %
 } %
 {\end{list}}
 
The idea is to let the examples counter run through each chapter and
only reset at the next chapter. For some reason, it resets itself in
environment changes (for example after enumerates, at each new
section...).
 
What am I doing wrong?
 
Thanks
 
K
