Sorry for the lack of code - yes, it does try to write to the
console.  From what I'm finding, this error may be due to the fact
that there is no "console" to write to when I'm logged off.  However,
I would like to be able to print to screen if I run the EXE in debug
mode (i.e. "myservice.exe debug").  Do you know of any way around
this?  Also, I need to get the output generated from an external EXE -
will subprocess.Popen cause problems if I use stdout=PIPE?  Thanks for
your help!
