No video on refresh or new link (IE7 & 8)

The problem is that when I refresh or go to another page with an flv file in it, the file either won't play and shows only a white box (JW4) or it plays but without the controls (Flowplayer). Using the generic player always works. Everything works in Firefox. IE7 & 8, though, have this problem. I'm using Flash 10, and the videos are encoded with Flash 7. I've tried using direct embedding and SWFObject 2, but it's the same results.

After doing some searching around, I found several pages that basically describe the same problem as mine. This is one of the first hits:
http://groups.google.com/group/swfobject/browse_thread/thread/c2fddcc3fc...

That seems to be the same problem because if I clear the cache everything works fine again for one page load. Also, since people (myself included) have this problem regardless of the player used, I figured going to the developer of the player wouldn't help much.

So, my question is am I doing something wrong? Or is the fix posted in the above link the necessary workaround? And if it is, how would I implement that within the SWF Tools module (I'm not a php programmer or anything, by the way)?

Thanks!
