Details:

On my movieClip I have a rollOver & rollOut effect with the following script.

txt1: will easeOut larger/ easeIn smaller
txt2: will fade in.

Script:
txt1.onRollOver = function() {

                gotoAndPlay("on");     };

txt1.onRollOut = function() {

                gotoAndPlay("off");   };

Problem:
In my flash file since this effect is done on keyframes if you rollOver the movieClip the easeOut/easeIn on txt1 effect will stick on the stage and it doesn’t look clean.

Can someone offer me some advise on how i could go about this with hard coding the actionscript effect instead of using a static motion tween.

Thanks!
