Flash player unexpectedly stops playing MP3 in IE7

Issue Summary

Hi,

We have a page of audio that is using the audio module.

With all of my Mac browsers everything works fine. However for people using IE7 (and apparently Firefox 3 on Windows) the player will automatically stop playing and revert back to the "stopped" state after a few seconds. The exact time it takes for the clip to automatically stop is different every time, but between 1-5 seconds usually, although sometimes much longer.

This seems to only happen when the player "loses focus", i.e., the user clicks something else on the page soon after clicking the play button, grabs the scroll bar, or starts using another tab, and only affects IE7 and Firefox3 on Windows. Safari and Firefox on Mac seem fine.

The problem also appears to affect only the above page, because we have been using the audio module without problems up until now on the following page

But I can't tell what the different would be that would cause one to work properly and one to be buggy.
