Topic: Can't view in Firefox - IE no problem

Tested on:

All's fine in IE.
FireFox: do not see the swf apear. Suggest to get Macromedia Flash.

But I DO have MF installed, can see the examples on example-page here.
I use SimpleViewer version 2.0 (Oct. 17th 2006 - version 2.0a  with fix for Firefox browsers)

Any ideas, what's wrong here?
