Win 98, Intel Pentium III 500 mhz with 128 mb SDRAM and a Voodoo 3 2000 PCI video card (truSpace 4 website recommends a Viper II AGP). I'm usually okay, but Poser often stops working if I do too many renders in succession. (?) I don't have to reboot my system, just Poser. It's Photoshop 4 that really crashes all over the place, with only one duplicate layer -especially if I try adding a "noise" filter to the tiniest section. I don't know if that's a RAM problem. -Talos
