IE8 will not load web pages at first request - If I click on a link or a Favourite menu item, it opens a IE window and shows the correct address in the address bar, and at the bottom says 'Done' but the page is blank. The only way I can get the page to load is to click in the address bar, and hit the enter key on my keyboard - therefore asking IE8 to try again. This always works. So why is IE8 not loading the page at first time of asking - why am I having to force it to try a second time? This is happening with many different sites - public and secure, and for many of our company's users. We are running Windows XP. I have installed all available updates for IE8. Pop-Up Blocker is off, Smart Screen filter is off. I've tried IE8 with addons disabled and there is no change. It even effects websites in trusted sites zone. Any ideas?
