Toolbar palette will not go away

A toolbar palette somehow managed to insert itself under the Ubuntu Unity top panel, thereby hiding it’s own toolbar. as a result I cannot kill the palette or move it. What can I do to remove this little problem. It shows up in all uses of LibO: spredsheet, document and so on

Apparently, this problem has not even been looked at. it is however a major problem as it can happen to anyone. The palette has lodged itself under the top panel on the left and top of the screen, cannot be moved or killed. It shows in all sections of Libre Office, Writer, Calc and so on.

The solution to this problem is on page 13 of the Calc documentation, it states to place the mouse pointer near the icons at th left top of the palette (which is actually a dockable window) and double click there… the window goes away.
