Gotta agree with most posters here.. my windows 98 machine was a nightmare with any app more complex than microsoft word 97. Bryce and Poser crashed all the time. Do yourself a huge favor and get Win2K or XP. I use XP and haven't experienced a non user related Poser 5 crash yet. (My machine got a little pissy with me when I accidentaly added 300,000 hairs rather than 3,000 to a section I was working on. ;)
