Version: (using KDE 4.3.0) OS: Linux Installed from: Debian testing/unstable Packages Clicking the plasma special button allows drag-and-drop of the different applets inside the panel, to change their position. However, if trying to drag the System Tray by holding the mouse button down on the Keyboard Layout Switcher, *the switcher* receives the click and switches the layout, thus not allowing the drag-and-drop. I believe that no item in the System Tray should be able to mask the mouse clicks when the panel is on settings mode. (I'm not sure what's the official name for this mode)
this is one of the flaws with the old xembed system and why we introduced the new dbus based protocol. we can't fix it for icons continuing to use the xembed system without doing something drastic such as hiding all those entries when going into configuration mode. the solution is for apps to move to the new protocol
