This shader problem is a biggie, I've reported it to e-on and they are aware of it, it's worse with V4 and M4. I'm using a pc so it's not a MAC thing!
I've gone back to using Vue6Infinite because of it, Poser figures are totally unusable in 7Infinite, all the textures are coming out just like yours, a kind of horrible green colour!!
You should raise a ticket at e-on, the more complaints they get, the quicker they'll get it sorted!

Injustice will be avenged.
