Hopefully some of those nice folks from Curious Labs will drop in on this post and offer a suggestion for fixing the load-time problem with SR4 (if there is a fix). Strange that some are experiencing it and some not, independent of the OS being used. By the way, I installed it in my Poser 5 "Root" file, which on my system is C:/Program Files/Metacreations/Poser 5. I assume putiing it in the Poser 5 folder is correct rather than installing it in just the Metacreations folder, yes?
