Opera 7.21 Final for Windows

"Opera was the first browser to introduce a multiple document interface (MDI), making it possible to surf in several windows at once. Now Opera further advances this feature by introducing an 'Undo' functionality. If users now close a window by mistake, it's easy to recall by referring to the 'Closed' window history list now added to the menu or using a keyboard shortcut, Ctrl Z. Kiosk mode is reintroduced with Opera 7.21, as was previously implemented in Opera 6. Kiosk mode is a customizable browser setting to limit functionality, blocking menus, preventing downloads, or adjusting other system preferences. Opera's kiosk mode is the most secure way to restrict access appropriate for computer labs, libraries and other kiosk providers."
