Grüß Gott Corinna --

Thanks. I updated our development environment to the latest stable release via setup.exe, then I installed the snapshot "cygwin-inst-20120220.tar.bz2" per the instructions at http://cygwin.com/faq-nochunks.html#faq.setup.snapshots . After that, I was able to use lftp to connect via SFTP without any issues. I am a little wary of installing a development snapshot in production, though. When will the fixes in the snapshot will be rolled to production?

Best,



Michael
