Sorry, it is a white, not a black screen...;)

But nothing happens. Except: After a few seconds the window gets the name:
*** Application is meditating ***

I also checked my libraries because first I thought I had downloaded the latest sdl2-archive but have not installed it. But it seems I did: sdl2.library v53.4, sdl2_mixer.library v53.5.

Do I need anything else? Any library?

Thanks!
