Change Display Mode on CTRL-ALT-DEL

There seems to be a bit of a quirk with Window's Ctrl+Alt+Del. When a D3D11 window in exclusive fullscreen mode loses focus via Ctrl+Alt+Del, the desktop retains the display mode used by this window. If the resolution is too small, using the desktop becomes a bit obtuse.

I want to make sure that the desktop is returned to its former display mode on Ctrl+Alt+Del, but there's no message for it and I'm not entirely sure how to go about doing that with DXGI. Is this possible?

@ChuckWalbourn This issue isn't addressed on that page. – NmdMystery Oct 23 '14 at 20:18
Are you using ``MakeWindowAssociation``? What flags are you providing? – Chuck Walbourn Oct 23 '14 at 20:19
@ChuckWalbourn Yes, I'm using `DXGI_MWA_NO_WINDOW_CHANGES`, but I've tried letting dxgi handle everything itself and the same problem occurs. – NmdMystery Oct 23 '14 at 20:19
