Version: (using Devel) OS: Linux Installed from: Compiled sources When you put the panel to the top, and open it's configurator or calendar, and then coles it, it doesn't disappear fully. See screenshot: http://img706.imageshack.us/img706/8265/snapshot11.png It does happen only when the panel is top-placed.
