Version: (using KDE 4.4.1) OS: Linux Installed from: Fedora RPMs Steps to reproduce: 1. Open a konsole window 2. Run the 'yes' command 3. The konsole window becomes unusable, even Ctrl+C doesn't work 4. Open another Konsole tab or window. 5. It opens fine, but doesn't accept any input! Only way out is to start another terminal (like gnome-terminal) and then kill the 'yes' process. Then all open Konsole windows return to their useful selves.
I'm on KDE 4.5.3 on Fedora 14 and this problem no longer exists.
