Okay that way its better something wen't wrong with the submission :)
I altered my control/popen with MAXPDSTRING as Mathieu proposed and it did the trick, although as he mentioned it should block if a cmd is even larger than that.

best regards,
Pedro
p.s.: just tell me if its needed to re-submit to the tracker, I gotta learn how to use it once and for all!

Seems like a good time to take inventory on the options here, since there seem to be many:

flatspace/popen (aka control/popen)

moonlib/popen

motex/system

ggee/shell

To me, moonlib/popen looks better than flatspace/popen since it allows reading and writing to the pipe.
