cant hide traditional menu bar, organize/layout/menu bar has no effect, no details pane option

i have both the old menu bar "file, edit, view, tools, help" and the new
toolbar "organize, views, explore, etc.". im supposed to be able to turn off
the old menu bar.

im supposed to be able to turn it off/on by clicking "organize" button on
new toolbar and selecting "layout" then clicking "menu bar". this has had no
effect. also pressing "alt" or f10 has no effect other than underlining
options. also the classic control panel has had no effect. my layout options
are only "menu bar" and "navigation plane". there should be more like
"details pane". anyone else had these problems?
