Can you Feather a mask?

Hey All!

Is there any way to feather a mask in Flash MX 2004… I was trying to use a PNG as a mask because of the soft effect I need to use, but it didn’t work with PNG… so is there any way to feather a vector shape or use a PNG file as a mask, I’m really hoping there is… if not, any other suggestions would be sweet.

Thanks for helping out.
