Strange legend popped up at top of screen

[Josef Lowder]

I just had a strange thing happen on my Mandrake desktop. 
Must have done something to cause this, but I don't know what. 

A gray borderless task bar just appeared at the top of my screen 
with these titles:  [ File  New  Bookmarks  Desktop  Windows  Help ] 
Each has a pull down menu that roughly corresponds to the tasks 
listed when I click on the K-menu "Start" button - i.e. "K" 

Any suggestions how to get rid of it?  
I tried "unclutter" desktop ... tried right-click on it (no response) ...
