I had a friend that had a problem with BING taking over her email. By that I mean when she checked her email, the message box showed for less than a second and then 'search with Bing' replaced the message. She could not read her email. This happened on every email she received. It drove me crazy until I removed the Bing plug-in and her email went back to normal. I did a search for 'Bing took over my email' and others had the same problem.
