One thing you need to remember: Everytime you install something new, you need to run CorrectReference on that folder. I often put an outfit on a character and add the character to the library. I run CR on that new character. I install a new Poser resource, and run CR on that new stuff. If you don't do this, then you're likely to get a lockup where PBooost won't switch banks. If you get a lockup, you might need to save your figure, quit Poser and PBooost. Then run CR to fix the texture references. You can spend a lot of time correcting all your texture references in the beginning. But it's time well spent. You're not just preventing PBooost lockups. You're fixing literally hundreds of bad texture references.
