Pixilate Filter

[fractal cat]

Hi all....
I think one is a newbie to PS for a loooong time!
So, I know a little and know a lot less than would like.
My question is:
I cannot get the pixelate filter up. It stays grayed out. I am using CS4.
I have tried rasterizing the layer...nada
Created a new layer (trying to create snow)...filled with black, added noise, spaced, etc etc....now trying to crystallize the noise. Can get the pixilate....anyone know why?
16 bit 300 dpi
working on a mac
Thanks
Anne

that's supposed to read: Can't get the pixilate.....not can

you will find a lot of filters will only work in 8 bit mode

It is strange I know and I did not realise that until a while back when I was doing a project for somebody and they insisted it be in 16 bit.
