Credits / thanks to "atolboo" who posted this in the dutch forum after I was not able to get my right button menu function back on the desktop screen after I had disabled it "somewhere".
By use of Alt+F2 and typing 'desktopbehavior'I immediately was presented with the menu to restore this function, he made my day
