SWF Movie Behaves Differently Online and Offline

Hi,

I have an SWF file that works great when I publish it or view it in the Flash Player.
However, when I use Simulate Download, all the buttons' functionality gets messed up - for some reason, clicking them results in the playhead going to other frames than it's supposed to.
I've tried uploading the file to my website and the buttons don't work well there either.

Is there any reason for this to happen?

Thanks a lot!

Something happened to me similar to this. The movie was playing before the required frame was loaded. What I did was make a preloader to make it stop until it finished loading. Also, check the publish menu because changing the load order has caused some problems for me. I can't do much without seeing a fla(or even a swf) or anything :/

Thanks, I did fix my preloader and it works fine. Thanks!
