Windows itself is an offender in that regard - e.g. the setting to select when updates are (and aren't) installed is a modal dialog that itself requires confirmation. And on top of that, it has two time pickers, each of which has separate scrolling columns for hours and minutes, but then you also have to press the "Confirm" button to actually apply changes after you scroll. And if you just click away to get back to the dialog, it 1) doesn't prompt to save changes, and 2) doesn't apply them.
