TO USE THE PROGRAMM YOU HAVE TO ACTIVATE THE TURBO-MODE BY CLICKING THE GREEN FLAG WHILE HOLDING THE *SHIFT BUTTON* . Once the picture is generated you can zoom in by clicking somewhere with the white cursor. If you wish to have more iterations, you have to change "MaxWiederholungen", but do not do it while it is painting or otherwise the programm might crash. It does not zoom in very fast, but it works.
