Hello I have the identical issue. I've tried the same things you mention above to no avail. Did you ever manage to solve this? I'm not a fan of the Chrome browser, but at this point I have no choice, IE is basically "broken". Affected IE9, upgraded to IE10, still the same. Chrome however works perfectly. e.g. Request page in IE - hangs somewhere while loading. Giving you enough time to open up Chrome, copy and paste the URL from IE into Chrome to see the page snap back immediately in Chrome while IE carries on thinking about it and then often just gives up.
