Flash preloader freezes when refreshed in IE7

Question

Ok, I know there are a lot of known issues with IE7 and
active content, but this is a new one to me, and I am really,
really hoping someone may know what is causing this...
I have a small online web site set up in HTML, but I have the
portfolio section set up in flash .swf, and naturally, there is a
preloader for this .swf file.
I already have a java script code to override the "click to
activate" issue with IE7, so that issue is taken care of. The
preloader works fine initially in all browsers and that includes
IE7, BUT if the user navigates away from the portfolio using the
top nav bar, and returns to the portfolio, the preloader freezes at
what looks like 99% as the image i used is completely colored in.
In order to advance, the user must then right click on the flash
movie and select "forward" to get to the frame containing the
content. This only happens in IE7, clicking links back and forth
does not create adverse effects in any other browsing setup.
I have the preloader set up on frame 1 of Scene 1 in multiple
layers, and i have the bottom layer labeled "content" where on
frame one, it is an empty keyframe, and then on frame 2 of that
layer I have the main_mc movie clip with all navigation and content
placed, and all layers above that have been converted to empty
keyframes on frame 2.
Here is the AS3 code I am using for the preloader on frame
one of the main stage:
stop();
this.loaderInfo.addEventListener(ProgressEvent.PROGRESS,
onProgress);
this.loaderInfo.addEventListener(Event.COMPLETE, onComplete);
function onProgress(e:ProgressEvent):void
var loaded:Number = e.target.bytesLoaded;
var total:Number = e.target.bytesTotal;
var pct:Number = loaded/total;
loader_mc.scaleX = pct;
loaded_txt.text = "loading portfolio..." + (Math.round(pct *
100)) + "%";
function onComplete(e:Event):void
gotoAndStop(2);
I have also tried:
function onComplete(e:Event):void
nextFrame();
but that has caused no difference with the issue.
Any Ideas, tips or tricks?? I am a recent graduate looking
for a job, and I feel like this issue has potential to hold me
back...thank you to anyone in advance.

If your using javascript to ebmed the movie, try this
yourswfName.swf?t= new Date().getTime()
if php
yourswfName.swf?t= php echo date("Y-m-d H:i:s")
I call it a cache buster, you can make a function and have it
append to the swf file name. it is some caching issue with ie7 and
flash player 9 so your adding a timestamp to the end of the file
name, making the browser reload the video.
also if the video is already loaded, and the user comes back
to the page. It could be already loaded. Then there is no need for
the preloader. Mabey put something in your code that says if bytes
loaded == bytes total skip preloader and just play.
hope that helps ya
