Hi, It could be because some websites do not properly delete or expire the cookie files which they create upon your visit to the site. On browsers other than IE you may have to manually do it for the sites by going to '''Tools''' ('''Alt''' + '''T''') > '''Options''' > '''Privacy''' > '''Show Cookies''', look for hotmail, msn, live etc. and delete those cookie files and refresh the site. ...............................................................................................................................
