YEAAAHHH,
Here it is, smooth scroll works in both directions up and down, only minor problem which I need to fix now is (not a big problem for my intended game since it's a space shooter which goes in one direction only) , when I change directions it's visible. I find it difficult to explain with my english knowledge. See for youreself.
Anyway making some really nice progress (so I think atleast)
Greetings
Robert
