I ran into the same problem awhile ago. Apparently Poser doesn't know how to cope with a wealth or resources. One similar problem I'd found is that I'd click on one Pose folder, and it would load something entirely different. I've also had so many folders that Poser only showed the first 4-5 letters of any given folder name. That makes things almost impossible. Hopefully Curious Labs is aware of this, and has already fixed the problem in Poser 5.
