Overview
Comment:First attempt at getting two menus side by side Tricky bit was that have to re-create my_items. I thought I'd be able to re-use that for the sake of this test. But without recreating it the second menu is blank.

Enable switching between windows with left/right keys - Oh my, I've ended up using pointers to pointers already! Use this so can switch the menu/win "pointing" at with left and right keys and then scroll up down the active one. - Also means need to just use plain getch and not wgetch as don't want to limit input to one window. I still don't get what determines an active window. Is it just cursor position? check-in: db667542ca user: atomicules@lavabit.com tags: origin/master, trunk
