Are you sure you preserved the permissions of the contents of ~/.ssh? 
ssh might refuse to use them, if they are too open.

I've have recently updated the scripts I used to maintain the 
authorized_keys file, so it's certainly possible I've broken something.

But I have double checked and your public key from [1] is present.

Can you send me (privately) the output of 'ssh -vvv cygwin@cygwin.com 
alive' ?
