Doug, ex-iView and now at Microsoft, has responded at the iView forum:
We are aware of this issue in the Windows variants of Expression Media. This will be fixed in our next release.
Please do not ask me about other fixes and expected availability dates, as
1) I do not know all the fixes we will make, and I do not know the release date, and,
2) if I did know, I would not be at liberty to divulge that info anyway.
Until this is fixed, Windows users are unlikely to switch.
