That radio buttons is in the pick color dialog that pops up.
I'm very sorry, but I can not see neither an option "use default background color" nor a radio button "Background Color" in this Colors tab of Explorer Pane dialog
I suppose, that I might work with the wrong dialog. Could you please describe a bit more exactly, which way should I reach this dialog, which you mean?
