Hi cheffefrau ,
Which demo code you need? You can find all the source code in the download package below
Downloads http://www.cutesoft.net/downloads/folders/21904/download.aspx
If the demo works for you, I suggest you download the latest version and try again. (the above link is the latest versio too)
If the latest versio still get the same issue on your end, please send me the test page url. We will check it and get back to you as soon as possible.
Regards,
Ken
