Ok all thanks for all the replies, I will now try and summarise to exactly what the problem is and what I have done.
1) When I use the cleaner, logins/usernames disappear from the login page. Like forums, my googlemail etc. for example, I have to retype the email address or the login username, these disppear.
2) I do not have Autocomplete form history ticked on the Cleaner page.
3) I have moved over the sites concerned on the Options Tab/Cookies on the cleaner programme to keep the cookies.
4) I do not use the Private browsing on IE8
5) Autocomplete settings on IE8 are Address bar Ticked, also browsing history and Favourties, not ticked is Feeds and Use Windows Search for better result. Not ticked is Forms - Ticked is Usernames and passwords on forms, and Ask me before saving passwords.
any ideas what I should do now.
Thanks
