disappearing flash content

Hi there,

I am facing a similar issue...when I embed the file (and this is consistent for many courses, not just one), initially a few times, it will show the video in preview mode. However, after sometime, it will show the content placeholder even in the preview window, as if it keeps forgetting the reference path!! And since it doesn't even shows up in preview mode, its not the case of popup-blocker i guess!!

As a result, I have to delete the embedded file and re-embed it .

What could be the reason??

Thanks,
