   DXUT9/10 ALT+TAB from full screen
  Simple question here, (advice on fixing would also be appreciated):When running the DirectX SDK samples, the expected behavior of ALT+TAB from full screen should be to fully minimize the window. I get this effect when running the DirectX 9 samples, but not when I run the DirectX 10 and 11 samples. Under those versions, the window simply reverts to a windowed state instead of minimizing, and then goes into full screen mode again when it gains focus. Does anyone else get this issue?
