Please look at the fla.
*I want the mc_1 (the big one) on layer 1 to be visible first and the rest of the mc (mc_a, mc_b, mc_c) to be invisible on layer two. Then when i rollOver mc_a with the mouse it will show up and be visible. And then when i decide to click on it, it will tween up and mc_1 (layer 1) will go to be invisible (fading). And then when i click again on mc_a that was tween up it will tween back and the mc_1 will be visible again. And when i rollOut from the mc_a it will go invisible again.
Please look at the fla.
