THANKS for those who checked this on their system and found nothing  
wrong. But that was bad news for me.
I switched back and force between the versions of 2006-05-28 and  
2006-06-07 by replacing all context related files from cont-tmf.zip,  
taking care to first remove all the old contents, regenerating the  
formats afterwards. Definitely the 2006-05-28 works, the 2006-06-07  
does not work here.

At the brink of giving up I thought it should be metapost related and  
then found in cont-sys.tex some patches I had received earlier and  
these now had to be taken out. So back to normal!

QUESTION: is the issue related to these patches now resolved from  
version 2006-06-07 onwards?

These patches were:

"% PATCH FOR SUPPRESS "unknown"s IN METAPOST COMMUNICATION OF textext"
\unexpanded\def\startcolor
{\ifincolor
     \expandafter\doglobalstartcolor
   \else
     \expandafter\noglobalstartcolor
   \fi}
\unexpanded\def\stopcolor
{\ifincolor
     \doglobalstopcolor
   \else
     \noglobalstopcolor
   \fi}
and
"% PATCH FOR STANDALONE GRAPHICS WHERE textext WAS NOT WORKING"
\long\def\writecheckedMPgraphic#1%
{\ifforceMPTEXgraphic
     \global\MPTEXgraphictrue
   \else
     \global\MPTEXgraphicfalse
     \edef\ascii{#1}\convertcommand\ascii\to\MPascii
     \the\MPTEXgraphicchecks\relax % \relax is end condition!
   \fi
   \flushMPTEXgraphic % verbatimtex etc
   \writeMPgraphic{#1}}
