all's been ok till my son said yes to allowing something! to access the internet from zone alarm. when the pc starts up (after the black & white bit)there used to be a blue screen with the names of all the users. Now there's a small winxp box asking for user's name & password. It appears again when we log off & we now can't switch user. can anyone tell me whats going on & if i can change it back again?
When i go start/log off/ switch user, a box appears that says "this computer is in use and has been locked" then you have to enter your name & password "only the owner or administrter can unlock this computer"
