, I've had the exact same symptom... I know it has to do with logon... I'm not certain how exactly I changed it... had to do with Start
-->Control Panel-->User Accounts-->Change the way Users Log On or Off--> and I am now using both "use welcome screen" & "use Fast User swithching" in winXPpro and have all three buttons you mentioned "lit".
BTW, I have an "administrator" set when I reloaded the OS that has a password, and one other user, "phawgg" that has full priveledges an a member of the administrator group. I think winXP home uses a slightly different "thing" with power-users as a group, maybe. You might see "guest" as an option... that would be a limited use category that I don't presently use since I alone use my computer. Hope this helps more than hinders.
and keep askin' questions...we're all bound to learn that way.
