Jonathan you are all correct. I have upgrade all the code and everything is the same i spoted what Jonathan talked... The elements inherit visability so it seems like when move with the menu they inherit some visability (and it is done when it jumps from last to first) but when scroll everything is ok. How can bypass this inheritance from the autoAlpha? I have done it with puer opacity. But now i see that when the animation or tween of the menu is made for 10 sek it is ok when i done it for 100 it is mixed.
