Hi Hans,
Something has changed recently with the mkii color model, due to which
page backgrounds do not change. (I am guessing that this is a grouping
issue, but then colors are like a black box to me). Consider the following
example
\setuppapersize[S6][S6]
\setupcolors[state=start]
\definecolor [simpleslidestextcolor][s=0]
\setupcolors[textcolor=simpleslidestextcolor]
\startuseMPgraphic{simpleslides:MP:horizontal}
StartPage ;
fill Page withcolor 0.5white ;
StopPage ;
\stopuseMPgraphic
\defineoverlay
[simpleslides:background:title]
[\useMPgraphic{simpleslides:MP:horizontal}]
\starttext
test \page
\setupbackgrounds[page][background={simpleslides:background:title}]
test again
\stoptext
In MKII, the background of the second page does not change. This used to
work until a few months ago (around Dec, 2008) but stopped working after
that. (It does not work in the Jan 18 version that I have).
In MKIV, this works fine.
Aditya

this is one of those messy areas where no robust solution is possible
the same can happen with header and footers and such (it does not happen
with color in mkiv because we use attributes)
I wonder, if we add \page here we might solve this kind of problems but
it might also have other side effects ... let's do it for a while (i
probably need to move some code)
\def\stoptext
{\global\advance\textlevel\minusone
\ifnum\textlevel>\zerocount \else
\page % new, flushes headers, colors etc etc etc
\the\everystoptext
\expandafter\finalend
\fi}

Thanks. This works in the bigger examples that I have.
