Hi Casimiro,
I have a text-only mail reader, so I cannot see which line is in red.
I am afraid that I don't understand the problem. Is there a problem
with the stdOut from Squeak ("OSProcess thisOSProcess stdOut") or a
problem with the stdOut from the child process ("child upToEnd") ?
Sorry, I am confused.
Dave
