[Unison-hackers] Windows setup with PuTTY

[Kurt Petersen]

Hi 

I found a way to configure Unison on Windows (by MartinCleaver). 

When it executes I get this:

Contacting server...
The server's host key is not cached in the registry. You
have no guarantee that the server is the computer you
think it is.
The server's rsa2 key fingerprint is:
ssh-rsa 1024 27:bc:f5:bc:18:91:f3:e8:b9:a5:8a:30:25:59:e6:99
If you trust this host, enter "y" to add the key to
PuTTY's cache and carry on connecting.
If you want to carry on connecting just once, without
adding the key to the cache, enter "n".
If you do not trust this host, press Return to abandon the
connection.
Store key in cache? (y/n)

It seems to contact the server, and I want to answer "y" - but key
input is not recognized. 

Has anybody tried this? 

Can anybody say what is wrong since input is not recognized?

Thanks!
Kurt
