Strangeness: Cannot write to a file from a process created by Windows Task Scheduler ...

Seeing some really weird behavior and perhaps someone has seen something
I have a python script that launches as a Windows Scheduled Task. The
program simply opens a disk file and writes some text to it:
f = open("waiting.txt", "w")
x = 0
f.write("Sleeping: %d\r\n" % x)
x += 1
I've run it under my user account. I've run it as Local Account. I've
run it via pythonw and python ... only one way works:
When I run with full credentials (not local account) and python (not
pythonw) I get output in the file (and a CMD window appears while it's
running). In every other combination it creates the 'waiting.txt' file,
but doesn't write any output to the file. The length of the file is 0 bytes.
Anyone have ideas what could be causing this? I suspect it's blocking on
something, but I can't imagine where.
There is no stderr/stdout output anywhere in the program so it's not
blocking on anything stdio related (that I can imagine)
