Hmm....the help file for the automatic setting states... "Specifies that when you return to a page you viewed previously, Internet Explorer should NOT check to see whether the page has changed since you last viewed it. If you select this, Internet Explorer will check for new content ONLY when you return to a page that was viewed in an earlier session of Internet Explorer or on an earlier day."(empathise mine) So, it supposedly isnt checking in auto mode either,untill your next session. (I clean out the cache every time I get off the net anyway)
