Uh, I appreciate your response, but the problem also occurs without any use
of Digi-anything products. If I am using morerows, I can create a full (not
jumbo) sized HAM image in Sculpt 3D, save it and then load it, all in one
session. The screw up happens entirely in Sculpt 3D. If it also happens in
DigiPaint, well then DigiPaint has a problem too. I can't really blame Sculpt
3D for either problem, it seems to me that overscan support is a grey area.
But then, if the Amiga 3000 comes out with 1kx1k graphics, I suppose it won't
work then either. So it ought to be supported now, 'cause its going to have to
be supported later.
