At the moment, I actually have things working the way that I need to with
regard to the multi-threading. I am not sure that it is stable since I am
only working with a simple test case that (more or less) acts like the full
framework. So far, I have created one window from a spawned thread and
successfully processed keyboard and mouse events in it, but there is still a
lot more that I have to do before I will know for sure that things are going
to work for me.

That is a very interesting idea. I had not thought of that at all, and I
will definitely ponder it some more. Thanks for the feedback.
