Если поменять
left, Yscreen,xold,yold и тд на int то компилятор пишет подобные варнинги:
105 [Warning] converting to `int' from `double'

[Obey-Kun]

Всё же в варнинге написанно!

double wndSizeX, wndSizeY;
double left, bottom;
double Xscreen, Yscreen;

Это должны быть int. Вы себе представляете линию толщиной в два с половиной пиксела?

Есть какие-нибудь предположения?
