Thanks for the answer :-), the problem is though if I try to run python -h,
I can see the output, but python --version won't work.!!!! I can't figure
out why a particular flag works and the other one does not!
[code]

program="python";

arguments << "-V" ; //arguments << "--version"
[/code]

does not work

[code]

program="python";

arguments << "-h" ;
[/code]

works!

Also, I want to run external programs and read their stdoutpout and
stderror. can I read in both into the same text box?
