Hi, on a network which internet access pass through a proxy server when IE8 loads it ask for proxy credentials as it should, but when going to different sites it continues to ask for the credentials even as they were correctly introduced the first time and the "save credentials" box is checked. This behavior is unique to machines with Windows 7 RC and Internet Explorer 8, as the combination Windows Vista, Win XP and Windows server 2003 with internet explorer 5,7 and 8 doesn't ask for proxy credentials after the first time. Is this a known behavior in Windows 7 or are we missing some configuration to keep the proxy credentials through the whole session?? Thanks in advance.
