Layers don't repeat in Mk IV

Layers don't repeat in Mk IV

I've been trying to use layers for a simple logo that repeats on all pages.
Something along the lines of the code below:

\definelayer[mybg][x=0mm, y=0mm,width=\paperwidth,
height=\paperheight,repeat=yes]
\setlayer       [mybg]
                [hoffset=1cm, voffset=1cm]
                {\framed[frame=on, width=3cm,
height=2cm]{\externalfigure[cow][width=1cm]
}}
\setupbackgrounds[page][background=mybg]

\starttext
\dorecurse{6}{\input tufte\par}
\stoptext

It works as expected using Mk II but does not work under Mk IV: The layer
appears only on the first page.

Please Help,
Derek

\definelayer[mybg][width=\paperwidth,height=\paperheight,state=repeat]

My file now contains:
--------------------------------------------------------------------------------------------------------------
\definelayer[mybg][width=\paperwidth,height=\paperheight,state=repeat]
\setlayer    [mybg]
        [hoffset=1cm, voffset=1cm]
        {\framed[frame=on, width=3cm,
height=2cm]{\externalfigure[cow][width=1cm]
}}
\setupbackgrounds[page][background=mybg]

\starttext
\dorecurse{6}{\input tufte\par}
\stoptext

It still does not work(still layer only on first page in Mk IV). What am I
doing wrong?

With Thanks,
Derek

A typo in pack-lyr.mkiv for the \dodoflushlayer macro.

In MkII a line of the macro is

        \doifnotvalue{\??ll#2\c!position}\v!yes
          {\doifvalue{\??ll#2\c!repeat}\v!yes\!!donecfalse
           \doifvalue{\??ll#2\c!state}\v!repeat\!!donecfalse}%

while in MkIV it's

      \ifx\@@currentlayerposition\v!yes
        \edef\@@currentlayerrepeat{\csname\??ll\currentlayer\c!repeat 
\endcsname}%
      % \edef\@@currentlayerstate {\csname\??ll\currentlayer\c!state 
\endcsname}% actually this is already set
        \ifx\@@currentlayerrepeat\v!yes
          \!!donecfalse
        \else\ifx\@@currentlayerstate\v!repeat
          \!!donecfalse
        \fi\fi
      \fi

MkII expects position ≠ yes while MkIV continues only when position =  
yes
what's wrong, you can add \unless before the \ifx and the layer  
mechanism works.

      \unless\ifx\@@currentlayerposition\v!yes
        \edef\@@currentlayerrepeat{\csname\??ll\currentlayer\c!repeat 
\endcsname}%
      % \edef\@@currentlayerstate {\csname\??ll\currentlayer\c!state 
\endcsname}% actually this is already set
        \ifx\@@currentlayerrepeat\v!yes
          \!!donecfalse
        \else\ifx\@@currentlayerstate\v!repeat
          \!!donecfalse
        \fi\fi
      \fi
    \fi
