Recently I started having this problem on *multiple computers*. Clicking one\nof the tabs in MSN Messenger 6.2 (specifically CNBC on MSN Money) frequently\nprompts me to sign in (displaying a login web page inside the Messenger\nwindow). After I sign in manually, it displays my stock quotes just fine.\nBut, after refreshing a few times, it prompts me that Passport login form\nagain. This is really annoying, as Messenger is supposed to automatically\nsign me in using the Passport I use in Messenger.\n\nI never had this problem before about two months ago. Does anybody have\nexplanation for this?
