Poser 5 is a PITA. Way too many "new" features don't work or are so buggy they can't be used. Dyn Hair... Can not be used for anumation. Collision detection on hair does not work properly. Cloth room will "Just Quit" after a few frames. FireFly... "Fire Flaw" and "Stoned Sloth" come to mind. Walk Designer seriously messed up after SR3. It only loads the first few blends and frequently crashes. I'm not a real fan of V3, It is very complex, but at least it works as DAZ advertised.
