Version: (using KDE KDE 3.5.2) Installed from: Debian testing/unstable Packages I don't know when this "feature" appeared, but in KDE 3.5.2, when you minimize a window, it will stay in front of the ALT-Tab list. Previously, it would be moved to the end of the list, but now the minimized window will be right back when pressing and releasing ALT-Tab.
