Interesting. So some games don't call it? But are you sure exclusive
mode is the default cooperative level? It would seem odd to me if it
was.

In fact, on this page, it says that background and nonexclusive is the
default:

The defaults could probably also be set in alloc_device instead of
explicitly checking in dinput_window_check. Though then the app's bad
behaviour wouldn't be warned about, but since that page does say that a
default setting is provided, perhaps it doesn't need to be something to
be warned about anyway.
