 My latest theory, such as it is, is that it is a cygwin issue or a
 cygwin/xemacs interaction.  My last cygwin upgrade ran into a
 ssh-agent problem (Could not open a connection).  I went back to the
 previous release for everything to get past the ssh-agent problem. 
Was this on Win9x?  If so, the ssh-agent problem has been fixed in
Cygwin snapshots, or you can wait for the next release.  (I don't know
when that might be.  Probably within a couple weeks.)
Hope this helps.
