• Answer:

  This has been happening for some time now, Yahoo are working on it they say but for now try this.Recommended fixes for the many current problems include Update Adobe Flash Player Internet Explorer and Java script . Clear Explorer cache, cookies, and browsing history. Some find that a return to classic mail improves things. You could also try an alternative browser. Hope this helps
