Image transparency screws up when tiled over 10+ layers..

[volcom]

hello,

im trying to create mulitple images on top of one another to build an object using pixel graphics, therefore i need transparent images. problem is once i layer over 10 transparent png-24 or gif images, the 11th image causes the first image to be blocked out (as if the 11th image has a background over the first image). does anyone know what i am talking about?

is this a known issue with flash?
i have searched the forums and havent found anything talking about this..
please point me in the right direction if i missed it.

i am using flash mx 2004

thanks alot

Well probaly its because there are so many layers and pixel infront of it it would block out the 1st one

for example i am trying to replicate a pixel person made up of many different objects, such as arms, legs, hair, etc...
each image is seperate, all the same size of 15x50 pixels, but only the object in each image is coloured with the rest transparent... (so you can see through to the object below)
but once i get up to 10 layers of transparency the first layer gets covered.
