Hi Christoph,

OSProcess for Windows is incomplete and most of the OSProcess/CommandShell
functionality that you see on unix (Linux, OS X) is not going to
work.

Levente's ProcessWrapper package may be more suitable:
  http://www.squeaksource.com/ProcessWrapper

I'm assuming you are running a Windows VM. If you are using a VM
for Linux, I don't know what will happen, but Windows does not
support the unix fork() semantics so I expect that there would
be limitations.

Dave
