I use yahoo as my start page. each time I start a new browser session I get a blue box that says JavaScript application, Invalid user-name/password. Try entering your email address as your user-name. I have to log in with email address and password every browser session even though the box for 2 weeks is checked. I have downloaded the latest version of Firefox and re downloaded Java, Have cleared all browsing history, cookies, cache etc. I do not have this problem if I switch to internet explorer.
