    Update to Alleged Information and Security Issue with Mouse Position Behavior

    • 72 Comments
    Over the last few days we’ve seen reports alleging abuse of a browser behavior regarding mouse position. Microsoft is working closely with other companies to address the concern of mouse position movement. From what we know now, the underlying issue has more to do with competition between analytics companies than consumer safety or privacy. We are actively working to adjust this behavior in IE. There are similar capabilities available in other browsers. Analytics firms can expect to do viewpoint...

    Building World-ready Applications in JavaScript Becoming a Reality
