Login to my server with SFTP and Filezilla

I installed authorized keys on my server, and have no problem logging in from my laptop with my new public key from a terminal.

I have just migrated from a Fedora 11 GNOME desktop to OpenSUSE KDE. Previously, a popup used to come up where I’d enter my public key password in Filezilla using SFTP when I asked to be connected to a site of mine on the server.

However, with KDE and Filezilla now, I cannot login without setting a specific site password in Filezilla File Manager, and login is refused. Ofcourse, if I enter the specific site password, it is alright.

Have I missed something here?
