This is actually what I call "a little dirty code". This happens as far as I
understand because child window doesn't update if it gets overdrawn. But in my
practice, including a lot of work with Lightwave and some other professional
software that uses Direct3D/OpenGL child windows this problem proved to be
minor and mostly cosmetic. Anyway, this is a lot better than working with
these programs in VMWare! Besides it shouldn't be very hard to fix this minor
bug later.
