Well, I've resolved this problem by other means, but I thought I'd post it out of curiosity. I've been working on a photographic studio. The light-stand/boom stand figures are posable with parented spotlights, so you can actually point the flash-head and get the correct lighting. Each figure's light has a unique name and matching unique shadow cam. So, all went well until I was testing. I loaded 2 of the same figure, knowing that the 2nd one would inherit the 1st one's light, (I was trying something out). What I didn't expect was that when I tried to delete the light or either of the figures, poser (P4) froze on me. So, to recap. Open 2 instances of a figure with a unique parented light. Try to delete the light or a figure. Freeze. Has anyone else ever had this? mac
