[Enigmail] Troubles in Windows 7

[James Rome]

I am running the nightly build of Enigmail for Thunderbird 3b2 inside
Windows 7 running inside Parallels on my MacPro.

I pointed Enigmail to C:\cygwin\bin\gpg.exe. But when I get an encrypted
massage, I enter the password for the private key, and nothing
happens--the message is still displayed encrypted.  The error console says:
enigmail> C:\cygwin\bin\gpg.exe --charset utf8 --batch --no-tty
--status-fd 2 --
decrypt --passphrase-fd 0 --no-use-agent
gpg: WARNING: using insecure memory!
gpg: please see http://www.gnupg.org/faq.html for more information
gpg: malformed CRC
enigmail.js: Enigmail.fixExitCode: Using gpg and exit code is 256. You
seem to u
se cygwin-gpg, activating countermeasures.
enigmail.js: Enigmail.fixExitCode: Changing exitCode 256->0
enigmail.js: Enigmail.decryptMessageEnd: Error in command execution

Everyone else canj decrypt these messages.
A also tried the gpg inside gpg4win, but with similar results.

I can decrypt messages that are attachments OK. But if I try to decrypt
and display them, I always get a permissions error while making the temp
file.

How do I get this working again?

Thanks,
Jim Rome
