Hmmmm. I've moved Poser around--even made a copy of it. It launched from where ever I put it without having to uninstall/reinstall (which had also been mentioned in previous threads). And I'm on XP. BTW, The first time I did a move, I used a mover program and it changed the case of all the directories ... a major pain in the a$$ I'll tell you since Poser is case sensitive.
