I have recently installed Cairo-Dock and find it to be very good. I was attempting to add a sub dock (with no success) and somehow managed to add a new launcher to the main dock with no icon or target.
When hovering over the newly created blank spot on the dock, the blank icon expands and the words "new launcher" appear. I can not right click on it to modify or remove it.
Any suggestions on removing the new launcher with n o icon or purpose as well as any input on adding sub-docks would be appreciated.
What I originally wanted to do was add an "Open Office" icon with a sub dock.
