I have a Surface RT - I have been browsing a site but I know one page on it has changed but my Surface wont update the page - it always shows the old page. I have used the refresh key but to no avail. The page is fine on all other PCs and my ipad but on the surface it still shows the old page. I have deleted all history etc and rebooted but it stubbornly won't refresh. How can I force it to refresh a page?
