OK. Well, it's good to know one way or the other. Now I can stop
getting my hopes up. :-) Thanks for the info.
Mike
Sorry, by "future release" I meant "after Vista ships".

Well, for testing purposes, I can see about using a WMA file or using a different application. Unfortunately, I am not in control of 3rd party applications, so if I want to use this with a DVD player app, for example, there's nothing I can do. As long as you're confident this will be fixed in a future release (before Vista ships, that is).
