What version of the OS are you using? When was the last service you had on your machine? Have you contacted Melco about the issue and tried their suggestions? OK, I think that's enough questions for now :) =========================================================== The AmayaUsers Mailing List Website: http://www.amayausers.com Discussion Board: http://www.amayausers.com/boards Subscribe/Unsubscribe: http://www.amayausers.com/list ===========================================================
