Hmmm... PBooost itself IS XP compatible... In fact, I've written it on a machine running XP. With some XP installations, Windows locks the runtime folders while Poser is running (the folders, not the files!) so PBooost, on these systems, is slightly limited. However, see the customer feedback against PB... it's all from XP users! Try the PBooost NT Compatibility tester and see how your system stacks up. You might be surprised! Even if you can't switch banks while Poser is running, you can still enjoy many benifits.
