Left shift in tabulator

Left shift in tabulator

[Tobias Burnus]

Hi,

using an older ConTeXt (around Jan. 26) everything is fine, but using
2000-01-31 or ver: 2000.2.15, I get some ugly results:

the entries in
\starttabulator[|r w(3mm)|p|r|]
\Frag{1.}{Eine "Ubersicht "uber den gesamten Stoff der Vorlesung wurde am
Anfang gegeben.}{\SixBox{0}{4}{2}{0}{0}{0}{1{,}3}}

are shifted to the left entry for entry. This doesn't happen, when the MP
graphics are not produced and only empty frames are drawn.

\def\GBox#1%
  {\hbox{\raise1.25ex\hbox{\tbox{#1}}}}

\def\Frag#1#2#3%
{\NC #1 \NC \vtop{#2} \NC \GBox{#3} \NC\NR}

\def\SixBox#1#2#3#4#5#6#7{%
\startuseMPgraphic{foo}
verbatimtex \setupbodyfont[ams,ss,9pt]  etex
sv := 2.2;
pickup pencircle scaled 0.7pt;
draw (0,0)--(101*sv,0)--(101*sv,30*sv)--(0,30*sv)--cycle;
%...
\stopuseMPgraphic
\useMPgraphic{foo}}

Any ideas? If needed be I can provide a complete (ex)sample.
