Can you upload a screenshot of the rectangle. Please. <div class="gmail_quote">On Sep 30, 2014 7:34 AM, "Lutz Andersohn" <<a href="mailto:landersohn@gmail.com">landersohn@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">The xfce4-panel is sort of similar to what you know from Windows as status bar. Do you have a bar at the bottom with some icons on it? At the top? You can do a right clock on it and click "Settings" (may be "preferences") and see how many panels you have. You probably want to keep panel 0. If you have a panel 1 (drop down list up top in the settings dialog), you can probably delete it.
