LOL Well I don't see why the shirt made Sydney go Gumby but I can try recreating that in Poser 7 and doing a screen dump if you like. Who knows which body part will rubberise next though. 

First it was her neck, then her right arm. How the dynamic shirt casued that is beyond me, but I heard there may be issues with hitting the cancel button on simulations which might explain the gumbyisation of figures in the clothroom.
