There is a way to throw out preffs and Poser makes new ones the next time you open it up. Sometimes these preffs files can get corrupted so that is why you'd want to do this. Location of your preffs (I think)

C: Users: User Name: AppData: Roaming: Poser Pro: 11

I can't rmember which ones you want to toss but you should save them in a folder somewhere as old preffs or the like before opening Poser.
