I tried different key types and different mounting modes. No help.
I figured out the problem (at last) by digging into the LSP stack
using Microsoft Anti-spyware. The problem was caused by part of the
Earthlink Total-Access package I installed so that I could dial up
while away from home. Most likely, it was the Anti-spyware part of
the package, although I wasn't able to do a partial un-install. I
would guess that one of the following is happening:
1. Earthlink's Anti-Spyware LSP is badly written (most likely)
2. Earthlink's Anti-Spyware believes rsync and ssh-agent to be spyware but
isn't telling me.
3. Earthlink's Anti-Spyware doesn't coexist peacefully with Microsoft
Antispyware.

Yes. This problem also went away when I uninstalled Earthlink. We can add
Earthlink Total-Access to the list of packages that are not compatible with
Cygwin. (Is there such a list anywhere?) When I get around to it, I'll try
re-installing Earthlink WITHOUT the anti-spyware component and see if it still
interferes.
I can't tell you how relieved I am to be able to do automatic synchronization
between my home PC and my laptop again.

This is the thread that got me wondering about what had installed
itself into my LSP stack. I was fearing that it was Norton Antivirus
(which I would have been loath to abandon), but had an Aha! moment
when I saw the Earthlink entries. The incompatible program was not
Aventail, as mentioned in the thread, but the concept was the same. I
read that thread before posting but read it again after your response.
Thanks for the help.

I couldn't figure out a way to create an attachment using the web interface to
this newsgroup. Sorry.
