Hi,

if I change the texexec perl script and add a exit 0 after line 
1767: 

[...]
#D   [       file=texexec.pl,
#D        version=2000.03.25,
[...]
              { print "                format : $MpFormat\n" ;
                $cmd .= " $MpPassString $MpFormatFlag$MpFormat " }
            $Problems = system ("$cmd $MpName" ) ;
	exit 0;  # <-----------------------
open (MPL,"$MpName.log") ;
while (<MPL>) # can be one big line unix under win
[...]

now I run 
texexec --interface=en --pdf mprun.tex
then
texexec --interface=en --mptex mpgraph.mp
and then
texexec --interface=en --pdf mprun.tex

the mpgraph.1 is generated.

only \runMPgraphicstrue is declared

this is the diff of the ls -l command between the first texexec 
and the second texexec command:

< -rw-rw-r--    1 gundlach gundlach      222 Feb 20 14:57 tmpgraph.tui

the < is after the second run.

...clueless :-)

Viele Gruesse,
