Hi Jan,

OK, I just traced the problem down, it's not a limitation on MoveTo(),
it just looked like that. It's really a limitation on the port origin.
LView::CalcPortOrigin(), chops off values greater than 2^14, thus it
was looking like my document was scrolling back around on top of itself;
page 20 looked like page 1.

I'll take the nice comment in the header of CalcPortOrigin() to heart,
and convert to image coordinates.

thanks for pointing me in the right direction,

david
