Cygwin emacs, tramp, and kerberos

[Charles Plager]

When I try to edit a file on certain computers, the first file I load 
works fine. When I try to load a second file, I get:

ssh_askpass: exec(/tmp/openssh/libexec/ssh-askpass): No such file or 
directory
Write failed: Cannot send after transport endpoint shutdown


This only seems to happen on computers where I use kerberos and ssh to 
connect. On other computers where I only need to use ssh without 
kerberos, I can open as many files as I want.

Any ideas?

        Thanks,
