Hiya... Thanks everyone for recommending my app... (Maybe I should have chosen a more memorable name... but it's actually "PBooost" LOL) Must let you all know that the next version (coming soon) will allow full compatability with XP under NTFS. It seems a bug in Poser itself is locking the library folders under certain circumstances. If any current PBooost users (with XP/NTFS) have the problem where they can switch banks for a while and then get the error "a program other than Poser is using the folders"... help is at hand. There is a temp workaround which involves editing the some cr2's etc... if you need details, let me know. Please note that this doesn't help if you're on FAT32... that's a case of "it either works all the time or not at all". Does this make sense?? H:)
