This is one awesome app! Grrrrr, I wish I could get it to work with Poser up. I spent several hours trying to figure it out, but I'm at a complete loss. There's lot's of services running in XP and I saw many could be changed in their properties. I didn't make any changes since I don't want to break my PC trying to fix one app. Any ideas? Another thing... I only log in with as one user. Does anyone have multiple users and log in as admin? Maybe that makes a difference to the file system. The Microsoft knowledge base is pretty extensive. I think I'll go look aroung there. Maybe something like this is covered. But regardless, PBooost is a "must have" utiltity since the the arrival of mat files. It makes using Poser fun again and not so fustrating. Thanks so much Hogwarden. And I do hope the support of those like me will encourage you to continue to try to get it working under XP.
