Captivate SWF (from FM) plays in IE, not in Firefox

Hi all, I'm using TCS2 on Windows XP.

I am  linking FM docs - and I have a Captivate SWF file in my FM doc. When I generated  the Captivate swf, I checked off the checkbox "Enable HTML". The video plays  fine in the FM doc and fine in the ensuing PDF.

In  Robohelp, I made sure to Import >> HMTL/XML file which imported my SWF and  HTML file.  I can see the video in the project files - I can see the first slide  (as the static image on the page) and then when you double-click it it starts to  play. When I preview that particular topic, it also works. I can see the SWF in  the files listed with all the screen shots (also in RH) under the Project Files  folder.

When the  generated webhelp is running/previewed in IE, the video works fine. You can see  the image that serves as its placeholder where it's supposed to be; when  clicking on it, it plays and all is well. However, in Firefox and Chrome =  different story. You can see the text "To watch the video, double click the  image below" - but no image. Nothing to double click on. Consequently, no  video.

Any help is greatly appreciated!

Thanks,

Adriana
