Somehing wrong with PNG inside SWF

Hi there!
The parts of my character consist from many PNG’s.
And only two of them displaying wrong. I loaded them into the game via swf.
Compression set to PNG, Allow smoothing = yes.

Here is how it looks like inside flash cs6 and then inside the game:


PNG formats of the legs is like in other parts of character, that displays ok.
Why is is happend?

Sorry for my English!

Ok. If I place png just inside moveiclip - all is ok. But if I rotate it -> bug.
I found a way to fix it: just make “create bitmap” from bitmap inside flash cs6.
But It’s not a good way…
