Version: (using KDE Devel) Installed from: Compiled sources Compiler: gcc 4.1.2 OS: Linux The lower panel is empty and I cannot drag any widget on it (they get placed below the panel and disappear). This is probably a known issue as the panel is currently quite buggy as I notice.
You have to drop them directly from the add-dialogue to the panel and not first to the desktop.
