Er... It already works with XP, procci. Has done since 1.3! With NTFS drives and clean texture references all works. MysticW... Unfortunately, CL wouldn't let me patch Poser to fix the bug... Poser has the bug, not PBooost:) CorrectReference sorts out the dodgy paths so Poser doesn't do it's lock bug thing. The majority of PBooost's users run XP-NTFS as an OS (using Poser 4) and have no problems with the system at all! H:)
