Thank you I think it could work with some method like this... but I can't really believe that gamestudio make it so hard do a simple scrolling function for a menue, because in many menues is a scroll bar... when anyone knows an easier way to do that please tell.
I just wanna explain once more what I mean:


Here you see how my menue looks actually.
The slider works as a well known windows slider, it moves all the green buttons.


And here you can see how it should look(this isn't make with code but I changed the image with paint). But notice: arround this menue you can see the rest of the game.

I think anyone had done this before me and can tell it.
