Oh, the lost and found thingie. I think I just thought, "Yeah right..." and kept going. Or I just forgot. Forgetting can really do wonders for moving you along in a game. Or stopping you dead.
Ingie, I think a couple people have played Anachronox in XP. One of them had a problem with the camera. It worked but he couldn't see the photos he took. I never did hear back if it was a problem or not. Dunno if that was XP or his particular system.
