p5 instability regarding new rooms is legendary. i've finally changed from propack to p5 only because of nested folders and the plug-in from reiss. normally this would be a free upgrade for p4 but there you go. :P i'm doing all renderings in max anyway. anybody who worked with v2 (let alone v3) won't touch don & judy anymore. i hope it will be the same with p5 when dazstudio finally comes. ;)
