OK. This is not my first time using a piece of software, but...I cannot even make a square! I click and drag, and get a dashed line showing the square I have made, but when I click, it vanishes. I cannot make the square stay, fill it, do anything. Same thing if I try to make a circle, and shape at all.
So what is it I am missing?
I have looked at the manual, even tried one of the quick-start exercises (Swedish Flag), and I can get my rectangles to snap to the grid, but they will not stay.
