I did a clean install of WIN 7 last September and tried IE 11 again and this problem still exists since it's launch. I tried IE 11 today and this problem still exists.
Things I've tried:
1. With a clean install of WIN 7 and with all updates installed for Windows and IE 11 in September 2014 I get this problem still. With all updates installed on IE 11 today I still get this problem.
2. Inprivate mode and no add ons mode doesn't fix this problem.
3. Rolling back to IE 10 fixed this problem.
4. Reseting IE doesn't fix the problem.
How to replicate my problem:
1. Open a new IE 11 window. Use any accelerator like bing search. After clicking a bing search link link I still have the option to go back to the original opened page.
2. Close the new tab that the accelerator opened.(you may have to do this a few times or open multiple tabs and close them)
3. Use the accelerator again on the first tab and click a bing search link. I no longer have the option to go back to the bing search results page.
