I don't know what I changed recently, but IE7 started complaining that I'm blocking cookies. I claim I'm not. I stopped all antivirus and antispy software. Windows firewall is on. I click the Sign In button on [URL]http://www.microsoft.com/communities/newsgroups/en-us/[/URL]. This produces the no-cookies complaint unless I set to accept all cookies. Even Low blocks cookies. On the Security tab in Internet Options, Internet is at Medium-high. I'm using Firefox to enter this post. Its "Accept cookies from sites" is on. Any thoughts on what I should look for? (Windows XP Home SP2)
