Проблема с отображением окон из Windows Runtime components.?

Question

[John_Nash]

Вызываю IDsObjectPicker из WinApi приложения. Сначала ругался на отсутствие вызова CoInitialize

Добавил. Диалоговое окно открывается, но в левом верхнем углу независимо от переданного hwndParent.
В исходниках с mfc (откуда собственно и взял) работает без проблем (можно даже GetDesktopWindow передавать). Окно по центру hwndParent. CoInitialize не требует.

В чем косяк, чего не хватает?

+Добавлено
Код выложил, но дело не в нем. Если экзешник запускающий этот код не mfc-приложение, то проблема есть. Видимо требуется какая-то дополнительная инициализация, которую я не выполняю.
