I am running Windows XP, IE7 and Norton Internet Security 2008. Recently, I have been plagued with a site logoff problem. The common symptoms are:
1. Logon to a secure site (e.g. PayPal, Bank or Mortgage)
2. Navigate to a feature where the site opens a second window (e.g. to display a file in PDF or display details from the previous screen)
3. Close that 2nd window
4. Subsequent navigation in the original window returns me to the login page as if I was never logged in.
Please point me to key settings in IE7 or Norton Internet Security that may be causing this behavior. I have other computers with the same software and OS that do not behave this way.
