Fixed bug #891 Mason Wheeler 2009-11-23 06:59:48 PST There's code in SDL_RecreateWindow specifically to handle SDL_WINDOW_FOREIGN, but it appears to have been overlooked in the allowed_flags constant. This causes the line window->flags = (flags & allowed_flags); to strip SDL_WINDOW_FOREIGN from the window's flags, which breaks some code in WIN_WindowProc in SDL_win32Events.c that treats foreign windows differently. This can be trivially fixed by defining allowed_flags as const Uint32 allowed_flags = (SDL_WINDOW_FULLSCREEN | SDL_WINDOW_OPENGL | SDL_WINDOW_BORDERLESS | SDL_WINDOW_RESIZABLE | SDL_WINDOW_INPUT_GRABBED | SDL_WINDOW_FOREIGN);
