Hi,
the code below is part of a program to draw the Mandelbrot-set. It works, if
the canvas is small (stamp-size). However, if the size is increased to 800x800,
the middle 1/3 of the image is replaced by a vertical grey bar. Any ideas?

you can setpixels from 0 to 255, 512, to 767, 1024 to ....
It doesn't matter in which language, you program, the bug is in windows
