Deleted the line <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN" "http://www.w3.org/TR/REC-html40/strict.dtd"> from the sub processProblem_htmlTOP. The required line is added bt the start_html command from CGI.pm. Having two DOCTYPE lines is invalid xml and caused a failure when used with CGI.pm ver 2.81 which outputs xhtml.
