Good Lord, an XP question already... I'm pretty sure that it is the same procedure as 98, at least I know in theory. Haven't played with XP yet however. Keep us posted on how stable XP is, I'm very curious after the ME flop.
Enviornment variables are set in MX the same way they are set in 2K. Not like 98. right click on My Computer, choose properties. Choose the Advanced tab and then click the Enviornment Variables button. You cand ADD, EDIT, MODIFY global and local variables. You will have to add your CLASSPATH. I suggest doing it globally in case you ever log in as another user or change your user settings.
Thanks for the tip. So far XP is doing great. Its nice no having to reboot all the time. If I were to do it again I would go with win2000 pro, the new interface and hand-holding in XP really bugs me. Cheers Randy
