ok, once upon a time, my pc would sit for hours and when i came back, would be just like i left it. if i was doin whatever, it would stay put indefinetly. now, for some unexplained reason, if i leave it for a while, it will kinda "time out" and ask me to click on a user name to continue. i click it and it will go back to where i was, but its slow about it and besides, i am the only user so i dont need multiple accounts. how can i get it to go back to like it was? oh yeah, its windows xp.
