I upgraded my system (LMDE) several days ago. Before upgrade I had one desktop panel on the bottom of the screen (unfortunately, I don't remember which version of Mate Desktop it was). Now with MDE 1.6.0 I see two panels (by default one on the top, and one on the bottom). One panel was more useful for me. Tried to find something in Mate config files about that, but unsuccessfully (I didn't work with Mate or Gnome DE before installing LMDE). Any suggestions?
