Nelson,

I've looked at TIMUTIL a bit this morning and found that it didn't
work exactly as I thought it should. In the Transparency settings
there are two check boxes. One is TRANSLUCENT EXCEPT BLACK, the other
is TRANSPARENT FOR BLACK. I would have thought that TRANSLUCENT EXCEPT
BLACK would have left the value of black at 0x0000, but it doesn't, it
changes it to 0x8000. However, if you check both boxes, it looks like
it sets the data correctly. I havn't actually looked at it on the
screen, but it looks right in a hex editor.
