I experienced the same jumping cursor problem than aother members ; why is this a "restricted posting" ,I do not understand ; also from this thread I am not allowed to answer or post anything (the thread about cursor jumps ) ; this is strange ; many of us meet the same problem , so , why prevent posting there ?

   When a question no longer has any activity, I wait for six months.  Then I either delete it or move it to the Answers section of this forum.  Once in the Answers section, no responses are allowed.
   I do this because some people have posted additional questions in a thread and additional comments that ignore the original question.
   If you want to post a comment to a question in the Answers section, please post it here (in the Questions section) and tell the URL of the question that you want to comment on.  If I think your comment has merit, I will add it to the thread you want to comment on.
