1) no prob... glad to hear you got it all working. Coolness.
2) You can override the TSvPrototypeGame.OnAppEvent event handler. There you can check SV.Minimized and SV.Active to test the application state.
3) If you want the application window to continue rendering when it looses the focus, set RenderOnLostFocus to TRUE and if you ever need to control the audio playback of the default audio engine, set GlobalFocus property to TRUE and audio will continue playing when the focus is lost.
