Hi kingarturo,
Thanks for replying, but I definately did upload the swf file (and it does work properly in IE). Feel free to take a look at my simple web site at this link:
http://www3.sympatico.ca/wchoi/niagara/tdn2000.htm
If you try to view the opening flash intro on it's own (the filename is tdn2000intro.swf), netscape will try to save it. Of course, if you do save it and then use netscape to open it from your hard drive, it works perfectly. I've also uploaded the fla file for that movie in case you wanted to view it for any clues. (same path, file name is tdn2000intro.fla)
I'm try to find out because I've been working on another site where a link will open a new browser window which is directed to an swf file. Unfortunately, it doesn't appear to work very well in netscape at the moment.
Thanks for your (additional) help,
Willie
