I believe Poser started life on the Mac, and got ported to the PC. This is why the .rsr is external to the cr2, hr2, etc.. there was no other logical way to port the mac's resource forks to a windows system without making the datafiles themselves incompatible between platforms. In other words, the whole .rsr thing is an afterthought, a hack that we just have to live with. Not nearly as bad as it could be, mostly thanks to Martin. -Adam
