I have two swf files: swf\_sender and swf\_receiver. The swf\_sender controls the swf\_receiver via java script.  
Everything works fine in IE however, the swf\_receiver doesn’t receive communication from java script if openned by Safari or Firefox.  
The first part of communication: swf\_sender - Java works ok (I tested it with alert() in Java) in all browsers.

Here is my Java interface code:

```auto
 
<script type="text/javascript">
 function getFlashMovie(movieName) {
  var isIE = navigator.appName.indexOf("Microsoft") != -1;
  return (isIE) ? window[movieName] : document[movieName];
 }
// call the sendTextToFlash function in AS3
 getFlashMovie("FlashName").sendTextToFlash("40");
</script>

```

Here is my AS3 code in swf\_receiver:

```auto

import flash.external.ExternalInterface;
function getTextFromJavaScript(FrameNumber:String):void {
 gotoAndPlay(FrameNumber);
}
ExternalInterface.addCallback("sendTextToFlash", getTextFromJavaScript);

```

I’d greatly appreciate any advice/ideas…
