In some cases the following trick had helped me to download file I wanted.
1. I tried to figure out the direct link to the file I wanted by scanning the html sources
2. I created small html file on my hard drive with the content

<a href="http://www.boohbah.com/zone.swf">1</a>

3.then opened the file in the browser, right clicked on the link and choose "Save Target As"

sometimes it worked
