my vote, regarding vista and tiger/leopard, would be to have all runtimes (and as many poser files as possible) in the documents folder or on an external drive, someplace where it's safe for poser to rewrite files. I also hope they fixed P7 so it doesn't try to rewrite files in the tiger/leopard apps folder, but maybe leopard is better at handling that. there were some betas out, but I didn't try 'em. another rumour would be that vista is a copy of jaguar/panther, hence I reckon if that's true, then there are gonna be permissions problems (or whatever they call 'em) in vista, and old daz installers won't work.
