This is the issue.

I have originally set the resolution to this cc.view.setDesignResolutionSize(640, 1136, cc.ResolutionPolicy.FIXED_HEIGHT);

and I have the follwoing menu: https://drive.google.com/open?id=0ByF2MyhrYuZVVU9nUlJib0w5REk

Under those conditions, everything works fine, scrolling is fine, all perfect, but in order to run the game on smaller screens I set the resolution to this: cc.view.setDesignResolutionSize(320, 480, cc.ResolutionPolicy.FIXED_HEIGHT);

and then scale it down to 0.4, the menu then looks like this: https://drive.google.com/open?id=0ByF2MyhrYuZVTUJyTHNvMGRBZHc

Here’s the code:

        var scrollVMenu = new ccui.ScrollView();
        scrollVMenu.setDirection(ccui.ScrollView.DIR_VERTICAL);
        scrollVMenu.setBounceEnabled(true);
        scrollVMenu.setAnchorPoint(0.5,0.5);
        scrollVMenu.setPosition(scrWidth/2,scrHeight/2);
        scrollVMenu.setContentSize(615,775);
        scrollVMenu.setInnerContainerSize(cc.size(700,2200));
        scrollVMenu.setScale(SFACTOR_X, SFACTOR_Y);
        this.addChild(scrollVMenu,1);

//…………..here I create the buttons for the menu…………….

        var menuLevel = new cc.Menu(arrMenuItems);
        menuLevel.setAnchorPoint(0.0,1.0);
        menuLevel.setPosition(cc.p(300,1120));
        menuLevel.alignItemsInColumns(3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3);
        scrollVMenu.addChild(menuLevel);

Any ideas?
