In pop_mail I have had to change line 202 from
Response.Write " <p><font face=""" & strDefaultFontFace & """ size=""" & strDefaultFontSize & """>Click to send <a href=""mailto:" & chkString(rs("M_EMAIL"),"display") & """>" & strRName & "</a> an e-mail</font></p>" & vbNewLine
to
Response.Write " <p><font face=""" & strDefaultFontFace & """ size=""" & strDefaultFontSize & """>Click to send <a href=""mailto:" & chkString(strREmail,"display") & """>" & strRName & "</a> an e-mail</font></p>" & vbNewLine
because if email mode is off you get an error trying to send mail with your mail program..<
