Sometimes, when I type SU and then start typing my password really fast, a few of the keystrokes will be echod to the screen -- usually when the system is only under moderate load and I'm not "expecting" it to be slow. It happens in X with gnome-terminal and also sometimes just at the console.
It's a real usability hassle. Suggestions? other than "expect that, and don't do it?" -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
