Close a floating window

Closing a floating RichMedia Annot is done by setting the "activated" property of the annot to false. I've set this up where I have a PDF form button that activates the flash. Then I make the annot on the page really small and hide it underneath the button. The code in the button just sets "activated" to true.Now for the diffucult part. Closing the floating player from a button on the SWF. The problem is that when the SWF ActionScript calls a JavaScript functon, the Flash player waits for a response from Acrobat JavaScript. If the call closes the Flash player then all heck breaks loose and Acrobat hangs or crashes. The trick is to decouple the actions with a timout script. I've been trying to figure this one out for a while and this solutions was just provided to me today by Joel Geraci, the Acrobat Technical Evangelist.

Use this line of code from the close button in the SWF
ExternalInterface.call("eval","app.setTimeOut('this.getAnnotRichMedia(this.pageNum,\"RM0\").activated=false;',100);");
The setTimeOut fucntion returns right away so the player is happy. Then the deactivation happens outside the context of the call for the RichMedia, making Acrobat happy.

Make sure you get all the quotes right, and the Annot name right. I've got this set up in one of my examples so that when the Rich media annot is setup, it finds it's own name and page number. Then sets them as persistent values. That way nothing needs to be hard coded in the SWF and it can be used on any PDF by just copying the RichMedia annot from one PDF to another.
