I am going to look at it.  I will probably make a lot of changes in this
area, but should be safe because I won't commit them.

Actually, I am not sure if it will or not.  The way it is set up, it can.
That is how I hoped to set the parent window for the button, by using the
window handle of the buttons parent in the call to CreateWindow, but the
buttons parent wasn't set yet.
