OK, it looks like I solved this. My external program is a python
program. I was starting it without the "-u" flag to Python, which
turns on unbuffered output. Adding the "-u" flag made the error go
away.
I found this tip in the docstrings of the _dumbwin32proc.py Twisted module.
Whoever put that note there, thanks!!!
Cheers,
Brian
