I think a little more then a patch is required for this. I'm not familiar with
their code. I've given them a C++ example of how they can get a window to
update. Its the beginnings of an observer design pattern as described in the
Gang of Four design patterns book.

That pattern is how I would do it. But the windows API is a monster. I admire
the work they are doing. The programmers on this project are far more familiar
with direct X then I am.  I'm just offering a suggestion to help further their
efforts.

Id be happy to make more suggestions. If they are welcome.
