CAUSE
This problem may occur if the Web site uses the post-check directive in an HTTP header to perform a lazy update of content on the Web page that you are viewing. For example, this problem may occur if the Web site uses the following custom HTTP header:
Cache-Control: post-check=3600,pre-check=7200
If the site administrator removes this custom HTTP header, the problem does not occur.

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
MORE INFORMATION
Post-check is a cache-control directive that is included with the HTTP Expires header. Web sites use the HTTP Expires header to control how Internet Explorer caches content on the Web site. Post-check defines a time interval (in seconds) after which an object must be checked for "freshness." This check allows Internet Explorer to display the content from its cache or in the Temporary Internet Files folder, and then update the cached copy of the content in the background (lazy update).
