I have updated and now it works. Thank you very much for all your efforts.

Now let's come to my second problem: the sidebar. Proudly, I present to you my
first MWE:

\definetyping[CPP]                                                             
   [before=\startsidebar,
     after=\stopsidebar]

\starttext

\samplefile{ward}

\startCPP
#include <stdio.h>

int main(void)
{
     printf("hello, world\n");
}
\stopCPP

\samplefile{weisman}

\stoptext

Can you see that there is an additional line before and after the code?
How can I get rid of these?

I greatly appreciate your help.

Thanks,
Johann
