Dear all,

after a long break I am returning to two larger projects of mine, and to celebrate, I upgraded
to ConTeXt from the current TeXLive.

To my surprise, mostly everything looks as before (which is good), but all my text backgrounds are gone.
A little search brought up Wolf-gang's example (from 1-20 2009)

\setupcolors[state=start] 

\definetextbackground 
[example] 
[location=paragraph, 
background=color, 
backgroundcolor=middlegray, 
frame=off] 

\starttext 

\input knuth 

\startexample 
\dorecurse{4}{\input knuth\par} 
\stopexample 

\input knuth 

\stoptext 

which doesn't produce any backgrounds - neither on my installation, nor at ConTeXt live.
What is the current way to produce backgrounds around text snippets? I'll need/want it
framed with rounded corners eventually, too.

Thanks!
