Same problem here on my mac (Dual 2.5) with Poser 5 after upgrading to Tiger. :( Worked fine in the beginning, but after the first crash it constantly keeps on crashing when I try use the pose bodyparts window. Very annoying!!! Any ideas if CL will fix this for P5 as well? I don't have P6 and I also don't see any reason to get it, since the new versions doesn't offere any enhancements that I have any use for. ;)
