MSB most significant bit. There's no problems with the utilities,
there's only 2 options for transparency in timutil, transparent for
black, and translucent except black. If you take your BMP and tick the
transparent for blck option, you should have no problems, as long as
your program is correct (which we don't know as you've not sent any code
fragments relating to sprite initialisation).
