working CONT configuration was: IIS 6.0: No status change to CONT requests

Can someone help me to a working CONT-configuration?

What I have: A working system with hosts grouped according to function, separated in hosts.cfg by page and include directives. 
I would like to add cont tests to a few hosts. If I put them in the same include file where
the server is first defined, it works. But the displayed table gets quite wide. So I put
those cont test in an additional file (see below #web-tests). When I do this, the
definitions from the file of the first host-definitions and those from the web-tests file
get combined, leading to the same wide display. Besides that after a short while the
dots for the cont definitions and the http column turn purple.

I tried different combinations of NOCOLUMNS,  GROUP(-)ONLY, NOCONN and changing the "0.0.0.0" in the web-tests file to the IP as already defined:: no changes.

Bonus question: The "Drucker" test for "linux-dmcl" shows nowhere. This is  copied from a message from 2006/8, where there was a reply "works like a charm" ...
