Aww nuts. I should have thought of that. I'll try again on a Win2K server.

Slap on the wrist for not checking the docs - in my defence I'm recovering
from a rather nasty cold, and I am following on from someone else's reported
problem!

Thanks Jason,

Dave.

No slap is necessary.  I'm sorry that my terse response did not indicate
my appreciation for taking the time to help out.

Thanks,

Jason and Dave, would y'all consider this a tested and supported
platform then? I'd like to correctly represent this in the ports list in
the docs for this release, but don't recall having seen a report such as
"Win+Cygwin work as well as they ever have"...

Thomas,

I have not done any 7.2 testing myself, but Dave reports the following:

Since I trust Dave, I feel that the above is an accurate characterization
of the situation.
