process.py problems

[Justin Johnson]

After replacing my process.py I still get an error with the dir command
(see below).

I'm getting some wierd results with normal .exe commands though. 
Commands that don't have much output come back just fine, but commands
that have more output, even if they don't take long to run necessarily,
seem to get stuck and just hang, never returning.
