Fixed bug #716 Armin Burgmeier 2009-03-15 04:35:45 PDT When I hold a mouse button down on another (non-SDL) window, then move the mouse over an SDL window and releasing the mouse button there, then the application does not receive an SDL_ACTIVEEVENT with state SDL_APPMOUSEFOCUS and gain 1. Furthermore, SDL_GetAppState() reports the application not having mouse focus until moving the mouse out of the window and back in again.
