Hello, i need heal to create a mask with as3.  
I dray a rectangle in the right place.  
But when i add the code to transform that rectangle in a mask the rectangle doesn’t keep it’s size, wich means that the mask doesn’t get the size i wanted.  
Any ideias?

I found out that this problem only occurs when the masked movie\_clip in nested inside others movieclips. but in this particular scenario i really need it to be inside other movie clips.

I would really apreciate some help, i don’t know what to do.

Thanks
