The latest version of Pboost is supposed to have dealt with the problems of file protection on Win2k, and Win2k and FAT 32 for us dual booters (I can only say 'supposed' because I haven't installed the latest version and played with it). Probably going to wait until I get P5 and see how well the new nesting works, but considering all the fricking content I have, I suspect that Pboost will find a new home...at least once Hogwarden has verified it works with the new Poser.
