This shows you all the passwords in your PROTECTED MEMORY (I had 1 entry which i deleted straight away (Outlook Express ID)) http://www.nirsoft.net/utils/pspv.html
Hmmm...reminds me why I NEVER answer "yes" to that question of "do you want teh system to remember your password?"
After i found that entry i scanned me registry for "Outlook" and found 1 key which i also removed....
