A radio menu, or option menu, lets you choose one of several choices,
and displays the current choice in the closed menu. It's the menu
equivalent of a set of radio buttons.

A combo box is a combination of a text field and a radio menu, and
displays the current choice in the text field.

Windows calls a radio menu a "drop-down list", while Mac OS X calls it a
"pop-up menu". GTK mistakenly calls it a "combo box", and then calls an
actual combo box a "combo box entry".

In both Ambiance and Radiance, I see no difference in appearance or
behavior between the Power Management Preferences "When laptop lid is
closed" menu, the CCSM Unity "Hide Launcher" menu, and the Software
Sources "Download from" and "Show new distribution releases" menus. If
you still see a difference, perhaps you could publish a screencast
somewhere demonstrating it?

The "Check for updates" menu is a combo box, and should not be. Someone
has just reported this bug. <http://launchpad.net/bugs/750507>
