/**

 * Usage:

 * ------------------------------------------------------------

 * There are three ways to use SWFFormFix, FULL AUTO, Auto and Manual mode.

 * To use either method you need to include this file in the 

 * HEAD section of your page like this: 



<script src="swfformfix.js" type="text/javascript"></script>



 * 

 * NOTE: If you want Javascript to call Flash, you need to make

 * a dummy object like follows:

 

window["myFlashObject"] = new Object();



 * Put this line directly above your call to SWFObject().

 * Replace "myFlashObject" with the ID of your object (the 2nd

 * parameter you give to SWFObject() ).  This will prevent your

 * page from dieing with an error like "myFlashObject is undefined".

 * 

 * --> FULL AUTO Mode:

 * This will attempt to find every Flash Movie that you have on

 * the page and apply the fix to each of them as the page loads.

 * It will poll the page for all the objects and determine if it

 * needs to apply the fix to them every 100ms until the page is

 * completely loaded.  All you need to do to use this mode is

 * include the script in the head of your document and set the

 * "EnableFullAuto" directive to true at the top of the script.

 *

 * --> Auto Mode:

 * This will attempt to find every Flash Movie that you have on

 * the page and apply the fix to each of them.  To use auto mode

 * put the following code before the </body> tag. More specifically

 * it needs to be AFTER your last Flash object.



<script type="text/javascript">

// <![CDATA[

	SWFFormFixAuto();

// ]]>

</script>



 * 

 * --> Manual Mode:

 * This lets you fix just a single Flash object if you don't want

 * the auto mode to try to fix every Flash object on the page.

 * This mode is faster than the auto mode and may work better in

 * some situations.  To use manual mode put the following code

 * after the Flash object you want to fix, where "myFlashObject"

 * is the ID of the Flash Object:



Example for normal EMBED style:



<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" width="200" height="100" id="myFlashObject" align="middle">

<param name="movie" value="myMovie.swf" />

<param name="quality" value="high" />

<embed src="myMovie.swf" quality="high" width="200" height="100" name="myFlashObject" type="application/x-shockwave-flash" />

</object>



<script type="text/javascript">

// <![CDATA[

SWFFormFix("myMovieObjectName");

// ]]>

</script>



Example for SWFObject style:



<div id="flashcontent" style="width:200px;height:100px;">This is replaced by the Flash movie.</div>

<script type="text/javascript">

// <![CDATA[

// Please note that the ID that you need to use for SWFFormFix() is the second argument in SWFObject().

var so = new SWFObject("myMovie.swf", "myFlashObject","200", "100", "6.0.0", "#ffffff");

so.addParam("quality", "high");

so.write("flashcontent");

SWFFormFix("myFlashObject");

// ]]>

</script>



 * 

 * Changelog:

 * ------------------------------------------------------------

 * v2.1

 *   Fixed IE cache bug that prevents JS -> Flash after refresh.  Now SWFFormFix

 *   rebuilds all the ExternalInterface() methods that were inadvertently destroyed.

 * v2.0

 *   Added FULL AUTO mode - just enable it below and include the script!

 *   Special thanks to Geoff Stearns from deconcept and onDOMload by Aaron Barker

 * 

 * v1.0

 *   Added the SWFFormFixAuto() function, very well optimized and fast.

 * 

 * v0.2

 *   Changed helper element from <input> element to hidden <div> element

 *

 * v0.1

 *   Initial release.
