Hi,
There is a bug with the "Play" parameter while I insert a SWF movie.
If I uncheck this parameter, the movie still play in Chrome/Mozilla.
This bug is  from this parameter that isn't added in the Embed tag although it is in the object tag.

Example :
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="150" height="150">
<param name="Movie" value="/aspnet-ajax/Editor/images/UserDir/Marketing/Reporting_banner.swf">
<param name="play" value="false">
<param name="quality" value="high">
<param name="wmode" value="transparent">
<param name="loop" value="false">
<param name="menu" value="false"><embed src="/aspnet-ajax/Editor/images/UserDir/Marketing/Reporting_banner.swf" width="150" height="150" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" quality="high" wmode="transparent" loop="false" menu="false"></object>

Thanks a lot
Chris.
