Seems to happen when firefly is used I shut down the system and re started clean loaded poser, verified the patch was in and then loaded a V2 and a steph. I was able to set the option to firefly with displacement off and do all polygons and once i hit render I got the exact same Caught C error as above, then poser locked out hard and the system needed shut down to regain control of the system. However with one figure the firefly will render. and poser4 render engine seems unaffected. The patch on an up note does now seem to render in poser4 mode faster.
