I setup a public key with passphrase via puttys keygen & its working with Putty directly to my Ubuntu OpenSSH server. I then tried to add private key (.ppk file) to filezilla & it stated password protected keyfiles are not supported yet, prompted to convert to unprotected file, I said no. Today I went to connect with normal password & got the below:

It's still trying to connect via public key. I downloaded psftp by itself to another directory & when trying to connect with just gregg@lnx it auto-prompted for key passphrase. Assume its auto-loading this info from the registry. I am posting this here to see if anyone else can test; because I would think they need to look at their code when you hit no it shouldn't do this. Or maybe my test with putty at first caused this?
Anyhow cool side effect: I found filezilla CAN accept passphrases/password-protected key files, as I put my passphrase for the private key in the password box & it accepts it & allows me in (I verified in the auth.log on ubuntu it took publickey)!!
