As I tried to figure out how the prog works, I encountered lots of problems. I was ecstatic at the beginning for this offer, but now ... I couldn't undo a lot of things I disliked or didn't right, as no button for undo or back was available. Then, when I tried to draw a simple circle, I drew it in a wrong position and I couldn't take it away from there by any means. I even tried the rubber, but it did nothing at all. And the circle covered my background, I couldn't make it transparent, and so on.
