some PLEASE give me a hand

I think my mind is going (HAL 9000). Windows XP and earlier, it's possible to "turn off" the "remember password" checkbox for Hotmail Logon in Outlook Express. Well I was futzing with my wifes NEW Toshiba Portege (no endorsement intended) and now I can't turn the darn thing back on! The "remember password" checkbox is greyed out. I went through all the administrator setting, outlook express and IE settings and I can't find the spot to TURN IT BACK ON. I even did a system restore to a few days earlier but NOOOOOOOOOOOO. I think my mind is going. Where is it? tlonder@comcast.net
