I am using 12.10, GNOME classic desktop. I believe the top bar (Applications/Places menus; wireless icon, sound volume icon, clock, Bluetooth icon, etc.) comes from gnome-panel, but I am not sure. Anyway, I accidentally dragged a folder onto it and now it displays a nice icon proving shortcut access to the folder. I'd like to remove this icon but I can't seem to be able to "drag it out of there".
You must use ALT-RIGHT CLICK to edit items on the panel in Gnome classic.
