Suddenly, I can't find an icon to change the color of an element. Am I losing my marbles or did it just up and disappear?
No marbles lost: It's hiding in the element dialogue box. Click on the properties icon:

How do I change the color of the wipout/erase image? Where did that go? I don't have that black box in the preview to select.
