I just installed clean ubuntustudio 12.04LTS 64bit ; I included all desktop environments to be able to try all and decide which I prefer.

When I log in I am presented with 4 panels with launchers and indicators etc. Two, Panel 1 and Panel 2 I can edit the properties of. The other two, one at top of screen and the second at the bottom I appear to have no immediate control over other than deleting icons, adding icons by drag and drop. There is no right click function enable, disable or modify these two panels/taskbars. They are light grey and smaller fonts are were pre filled with launchers and date time indicators etc.

How do I get control of these two to get rid of them or modify them for practical use; they appear to contain same info and launchers as Panel1 and Panel2 anyway
