Thank you very much. I'm glad you liked it.

Thanks for the suggestion, perhaps I'll do that when I repost it.

This is a more complicated question. The person who wrote
the original Java prog. had a very clever way of creating
the 3d effect. If you look at the bitmaps used, there are 4
separate complete boards. 1) with all white pieces, 2) with
all black pieces, 3) with all of a 3th color for marking
legal moves and 4) an empty board. First the empty board is
output completely then according to an internal table of
coordinates (they're different for each row) it copies 1
squire at a time from the corresponding position in the
appropriate image(1,2,3 or 4) to the screen. That is to say,
for every move an arbitrary block in one of the 4 images
must be moved to the corresponding coordinates on the
screen. From what I saw of drawBitmap it only drew the
complete bitmap. I just arbitrary decided to modifier a copy
of drawBitmap to do that. In the original Java prog. he did
it by 1st setting the clipping rectangle to the preselected
coordinates then coping the hole image, but, at the time, I
couldn't think of how else to set the clipping rectangle.
Any suggestion I'd be glad to hear them, I not well versed
on windows API.

I think this also helps to explan why few othello games are
done this way  :)
