|When you go to Tools > Internet Options it should open in the "General" tab.|
A little way down there is a "section" headed Browsing history. It says "Delete temporary files, history, cookies, saved passwords, and web form information"
Below this is a Delete button. Click that and ensure there are ticks in "Temporary Internet Files", "History" and "Forms data". Hit the new Delete button on that page and see if it helps. If not see my link in #10.
Always pop back and let us know the outcome - thanks
