We are trying to improve our Silverlight drag-drop framework to allow drag-drop between OOB windows (real Window, not ChildWindow). However, there is a problem in the Silverlight runtime that prevents us from providing the feature. We have filed a bug report, but we need more votes in order to increase its priority and have it eventually fixed in an upcoming service pack release.
Here is the link to the bug, please, vote for it:
Thank you in advance,
