Hi,

Judging by the code you posted it would appear that you are trying to use
the "Flash Satay" workaround:
http://www.alistapart.com/articles/flashsatay/
whereby you are using a small container movie "c.swf" to call the main movie
"movie.swf".

The container movie(c.swf) contains an ActionScript that loads the main
movie:
_root.loadMovie(_root.path,0);

While this may be a good workaround for validating XHTML document, it falls
short of getting around the EOLAS problems in IE6||IE7.  In either Browser
you will have the "Click to Activate and use this control" (IE6), or, "Press
SPACEBAR or ENTER to activate and use this control" (IE7).

To get around the EOLAS problem, you must load the Flash content from an
external
.js file.

"The Dreamweaver 8.0.2 Updater and Flash Active Content Update Extension
include templates and code for publishing active content under the new
guidelines. In addition, you can find more information in the Active Content
Developer Center."

Good luck,
