Topic: Simpleviewer 1.8 works in IE but not Firefox

I downloaded a clean copy of Simpleviewer 1.8 to test.

It works fine in IE 6 (I can see thumbnail images and large image).

In Firefox, the thumbnail boxes are empty and there is no image. I have Firefox 2 (with Flash 9) and I verified that Javascript is turned on. I also verified that I have the swfobject.js.

Are there any known compatibility issues with Firefox? if so, is there a fix?

Thanks in advance for your help,
Dianna
