There are several html files for different language version. Vector.html is the english version. If it is still not working, may be it is due to two lines I forgot to remove in the html file Please remove the following two lines: <meta http-equiv="Content-Type" content="text/html; charset=big5"> <meta name="GENERATOR" content="Mozilla/4.7 [en] (Win98; I) [Netscape]"> And it should work fine. I have change the ZIP files so there should be no problem if you ask the ZIP file again.
