Hey list,

I can't recall if either I explicitly changed something in my ConTeXt
typesetting or if this happened with the most recent version of ConTeXt
I pulled from Adam's PPA. I am using version 2011.11.02 20:10.

Here is a minimal example:
\definestartstop
    [CodeExample]
    [before={
        \crlf
        \setupbackground[frame=on,
                         before=\blank,
                         after=\blank,
                         corner=round,
                         topoffset=0.5cm,
                         leftoffset=0.5cm,
                         rightoffset=0.5cm,
                         bottomoffset=0.5cm]
        \startbackground
        \startlines
            },
     after={
        \stoplines
        \stopbackground
        \crlf
           },
     commands={\setupalign[right]},
     style=type]

\starttext
Hello World
\startCodeExample
\starttyping
Hello World Again
\stoptyping
\stopCodeExample
\stoptext

Here is the output:
