Witaj Stephen,

SW> I can say why, but maybe the final index was stored as the count (oops,
SW> off by one) or the loop copying the points has an off by one problem.

Thank you for your answer. I still don't known what was wrong but I
edit layer (.shp) in open_ev and save it. When I make new map file with
this new .shp all is ok, it is good show. Maybe wintopo save it in other
way/format (int, double, other round count).
Thank you one more time :]
