Strange opening docs in Microsoft Word with NVidia Broadcast running

I realize this may not be an issue with DOPUS but it seems involved, perhaps someone here has some inkling as to what is going on.

I have been using DOPUS and Microsoft Word for years, this behavior is new and only started in the last couple of days: if I double-click a Word document from a DOPUS lister, when Microsoft Word launches, Word's ribbon/toolbar is completely blank... it occupies space as if it would normally but there is absolutely nothing there, no buttons or menus or even Windows controls... just an empty white canvas.

If I launch Word from Windows, the application behaves normally, and if I open the same document from Word, it continues to behave as expected.

Likewise, if I launch Word by double-clicking a Word file from Windows Explorer, again it behaves completely as expected.

Seems like it may be related to NVIDIA Broadcast, behavior is normal after quitting that application.
