I have done something silly, and cant get out of it, and wonder if someone
can remind me how to resolve an issue.

My desktop originally had just white words under the icons, now I have a
blue square background box behind the white writing?
I cant for the life of me find a way of getting rid of the blue background
box, I looked in the advanced tab, and find I can change the colour, but get
shot of the box. Any ideas please
Bob
