If you are Dominik, I've got your email. I have not yet time to prepare a debug version. Sorry.
did you see my email, got yours from your website and sent a mail to you so that you can reply.
Can I have your email address, so that I can send you a debug version?
I think this is a bug:
If a long delay occurs during login (i.e. before "password: " query comes but username was sent, then the waiting dialog shows up "...still waiting, Abort" - but if the server then continues and sends the password request, the waiting dialog is not dismissed and the user can't dismiss it. There's sort of a UI deadlock. You can't enter password and you can't dismiss the wait dialog.
Thanks for looking into it.
