> I don't understand why exactly fceux creates this window, though. Ok, I'm dump. I tried three times to describe what happens here without boring everyone to death - and I failed. So I deleted everything I wrote. The gist of it is that fceux needs to use some hacks to get the best results with SDL for its use case and that prompts this new empty window (created by SDL). As I said in my other mail I don't really know which part to fix - fceux, SDL or dwm. If someone wants to look into this I can provide some pointers (and some boring as hell explanation). -- Eckehard Berns
