Hey, if a computer is that old, it's possible that it might not be practical to upgrade the computer. Some of the older computers can't be upgraded to current levels. It's hard to tell without more info. A computer with a 20GB hard drive might be fairly recent. However, in the time period where those drives have come, we've also moved to Windows ME. So this is pretty confusing. I started using Poser with Windows ME. I must say that Poser is absolutely terrible with Windows ME, and most likely with Windows 98. Poser just crashes or locks up whenever anything goes wrong. It's kind of like a spoiled child. That point became abundantly clear when I tried out the Windows XP "pre-release" version, then wiped my hard drive and reinstalled Windows ME till I could afford to buy Windows XP Home Edition. I agree that more memory is absolutely essential, as well as a larger hard drive. But you need to discover the maximum memory the motherboard can handle. And then I recommend Windows XP. A 20GB hard drive really isn't much. Mine filled up very quickly when I started installing all my Poser stuff. You have to also take into account the other stuff on that hard drive, and how much room Windows wants for a swap file, etc.
