I have XP Pro, 512MB RAM, P4, the latest Poser patch and I had the crosstalk problem (see my earlier thread "Please Help: Can't use Vicky 2 & Mike 2 together..." However, as I mentioned, it seemed to me the problem kicked in sometime after I had started working on a scene containing the 2 figures, although I simply may not have noticed the effect at first. Anyway, the null figure workaround worked.
