Oddly enough, Bryce 5.01 locked up on me tonight. First time in over two years. I had other problems though and had some app, wowexe, causing the problem. Firewalls were up. I had just been on the machine for about an hour when it happened. No sign of problems when I shut down the other day. I'll have to research this a bit. Was a huge memory hog and slowed icq down a lot. Irc and Poser worked just fine. I typically have Bryce, Poser, icq, irc, outlook, pbooost, norton, some audio controllers, grouper, P3D0, and a few IE 6 and some smaller apps going at once and rarely ever have a problem. Reboot fixed it. I RARELY EVER have to reboot.
